TJOFLAT, Circuit Judge:

The issue in this case is whether a district court order reducing a defendant's sentence pursuant to Federal Rule of Criminal Procedure 35(b)1 for the defendant's substantial assistance is a new "judgment of conviction" that resets the one-year statute of limitations for filing a motion to vacate a conviction and sentence under 28 U.S.C. § 2255.2 The district court held that its Rule 35(b) order did not reset the clock and dismissed the petitioner's § 2255 motion. We affirm.

A.

From 2001 to 2003, Robert Marshal Murphy, the petitioner, helped lead an "entrenched" Pensacola Beach-based conspiracy to distribute cocaine. A multi-agency law enforcement operation brought the enterprise to an end, and Murphy decided to cooperate. On December 12, 2003, Murphy entered into a plea agreement with the Government. In exchange for the Government's promise to move the district court pursuant to U.S.S.G. § 5K1.13 to impose sentences below the Guidelines sentencing range, he pled guilty to conspiring to possess with intent to distribute cocaine and to commit money laundering.4 After the district court accepted his guilty pleas and prior to sentencing, Murphy provided the Government with substantial assistance in its investigation of those with whom he had been trafficking cocaine.

Murphy was sentenced on April 28, 2004.5 Under the Sentencing Guidelines, Murphy's criminal history category was I and his adjusted offense level was 37, yielding a sentencing range for the two conspiracy offenses of 210 to 262 months' imprisonment.6 Because Murphy assisted the Government's investigation, the Government moved the district court pursuant to § 5K1.1 to sentence him below the Guidelines sentencing range. The court granted the motion and, on April 28, 2004, sentenced Murphy to concurrent prison terms of 90 months.

After sentencing, Murphy continued to assist in the investigation and prosecution of others involved in cocaine trafficking. As a result of that cooperation, which included testifying against co-conspirators, the Government, on March 8, 2007, moved the district court pursuant to Rule 35(b) to reduce Murphy's sentence. The court granted the motion on May 10, 2007. In a sealed order, the court reduced Murphy's concurrent terms of imprisonment from 90 months to 66 months. The court emphasized that "[i]n all other respects, the defendant's judgment of April 28, 2004, remains in full force and effect."

B.

On August 3, 2007, three months after the district court granted the Government's Rule 35(b) motion and over three years after the time for appealing the April 28, 2004, judgment had expired, Murphy, proceeding pro se, moved the district court under § 2255 to vacate, set aside, or correct his sentences. Murphy claimed that he had received ineffective assistance of counsel in connection with his April 28, 2004, sentencing. His motion alleged that his retained attorney had a conflict of interest, failed to object to factual inaccuracies in the presentence investigation report that resulted in a six-point increase in his offense level, and inadequately explained the money laundering charge to him. Recognizing that § 2255's one-year statute of limitations applied, Murphy argued that the time limit should run from August 14, 2006, when he first sought and received permission to review his file at the prison camp.7

The district court referred Murphy's motion to a magistrate judge who recommended that the court summarily dismiss it as untimely.8 Noting that § 2255 imposes a one-year statute of limitations, the magistrate judge concluded that the period began to run on May 9, 2004, which was ten days after the district court had imposed sentence and entered judgment, and the time for appealing the judgment had expired. Therefore, absent equitable tolling, Murphy's § 2255 motion had to be filed by May 9, 2005. Although Murphy claimed not to have reviewed his file or learned of the grounds for the motion until August 2006, nothing stopped him from reviewing the file earlier; thus, equitable tolling did not apply.

Murphy objected to some of the magistrate judge's findings and conclusions. Most importantly, he contended that the district court's Rule 35(b) modification of the sentence on May 10, 2007, reset the statute of limitations clock. Nevertheless, on September 12, 2007, the district court, adopting the magistrate judge's recommendation in full, dismissed Murphy's § 2255 motion as time-barred.

On October 12, 2007, Murphy sought a certificate of appealability. He pointed out that the dismissal of his motion turned on the district court's conclusion that his conviction became final on May 9, 2005, a conclusion that conflicted with this court's then-recent decision in Ferreira v. Secretary, Department of Corrections, 494 F.3d 1286 (11th Cir.2007). The district court therefore granted a certificate of appealability on the following question: "Whether granting a defendant a sentence reduction pursuant to Rule 35 constitutes a resentencing that re-starts the AEDPA time clock, allowing a defendant to collaterally attack his original conviction and sentence." This appeal followed.

II.

In an appeal challenging a § 2255 ruling, we review legal issues de novo and factual findings for clear error. Lynn v. United States, 365 F.3d 1225, 1232 (11th Cir.2004). Whether a § 2255 motion is time-barred is a legal issue. Drury v. United States, 507 F.3d 1295, 1296 (11th Cir.2007).

A.

Section 2255 allows a federal prisoner to seek post-conviction relief from a sentence imposed in violation of the Constitution or laws of the United States or if it is otherwise subject to collateral attack.9 In the Antiterrorism and Effective Death Penalty Act of 1996 ("AEDPA"), Congress created a one-year statute of limitations for § 2255 motions, running from the latest of four dates.10 28 U.S.C. § 2255(f). The relevant date here is "the date on which the judgment of conviction becomes final." Id. (emphasis added).

Section 2255(f) does not define "judgment of conviction" or "final." Nonetheless, we have concluded that when a defendant does not appeal his conviction or sentence, the judgment of conviction becomes final when the time for seeking that review expires. Mederos v. United States, 218 F.3d 1252, 1253 (11th Cir.2000) (noting that when no direct appeal was taken from the original judgment of conviction, the judgment of conviction became final when the time for filing a direct appeal expired); Akins v. United States, 204 F.3d 1086, 1089 n. 1 (11th Cir.2000) ("A conviction ordinarily becomes final when the opportunity for direct appeal of the judgment of conviction has been exhausted."); cf. Clay v. United States, 537 U.S. 522, 527, 123 S.Ct. 1072, 1076, 155 L.Ed.2d 88 (2003) ("Finality attaches when this Court affirms a conviction on the merits on direct review or denies a petition for a writ of certiorari, or when the time for filing a certiorari petition expires.").

At the time of Murphy's sentencing, a criminal defendant had ten days to file an appeal. Fed. R.App. P. 4(b)(1)(A) (2005) (amended 2009).11 Therefore, had the district court never granted the Government's Rule 35(b) motion, it is perfectly clear that AEDPA's statute of limitations would have expired on May 9, 2005, and Murphy's § 2255 motion filed on August 3, 2007, would have been time-barred. Murphy contends that when the district court reduced his sentence under Rule 35(b), it entered a new "judgment of conviction." We conclude that Congress has foreclosed this argument by statute, a conclusion that is confirmed by the decisions of our sister circuits and Congress's overriding intent in enacting AEDPA.

Rule 35(b) permits a district court, upon the Government's motion, to reduce a sentence to reflect a defendant's substantial assistance rendered after the entry of judgment. Fed.R.Crim.P. 35(b). In § 2255(f), Congress did not specify whether a Rule 35(b) reduction constitutes a new judgment of conviction or alters the finality of the judgment of conviction. But Congress did not legislate on a blank slate: "[W]henever Congress passes a new statute, it acts aware of all previous statutes on the same subject." Erlenbaugh v. United States, 409 U.S. 239, 244, 93 S.Ct. 477, 480, 34 L.Ed.2d 446 (1972). Prior to AEDPA, Congress, in 18 U.S.C. § 3582, specified how a Rule 35(b) reduction would impact the finality of a judgment of conviction.

Section 3582 states that although a district court may "modify" a "sentence to imprisonment" under Rule 35(b), a "judgment of conviction that includes such a sentence constitutes a final judgment for all other purposes."12 18 U.S.C. § 3582(b)-(c) (emphasis added). The plain and obvious meaning of this language is that a Rule 35(b) reduction has no effect on the finality of the judgment of conviction. See Hughes Aircraft Co. v. Jacobson, 525 U.S. 432, 438, 119 S.Ct. 755, 760, 142 L.Ed.2d 881 (1999) (explaining that statutory construction begins with the language of the statute and when that language "provides a clear answer, it ends there as well") (internal quotation marks omitted). The Senate Report accompanying § 3582 confirms that the plain meaning of the statute accords with Congress's intent. Congress explained that subsection (b) makes "clear" that though a prison sentence could be "modified" after imposition by way of "`three safety valves,'" including Rule 35(b), the "judgment of conviction is final." S.Rep. No. 98-225, at 96 (1983), reprinted in 1984 U.S.C.C.A.N. 3182, 3304.13

In view of the traditional rule that a final judgment in a criminal case includes both the conviction and sentence, Congress understandably sought to assure that the use of Rule 35(b) to modify a sentence would not impact the finality of the judgment of conviction. Had Congress not done so, a defendant could have argued that a sentence modification entitled him to a new direct appeal where he could challenge anything that could have been challenged on a first direct appeal.14 Congress short-circuited this by unambiguously declaring that a Rule 35(b) modification does not affect the finality of the judgment for "any other purpose." 18 U.S.C. § 3582(b).

Plainly, AEDPA's one-year statute of limitations falls within the category of "any other purpose." United States v. Sanders, 247 F.3d 139, 142-144 & n. 2 (4th Cir.2001). Therefore, a district court's reduction of a term of imprisonment under Rule 35(b) has no impact on the "finality" of a defendant's "judgment of conviction" and does not alter the "date on which the judgment of conviction becomes final" for the purposes of the statute of limitations. Id. (internal quotation marks omitted).

So far as we can tell, every circuit to have addressed this question agrees with our conclusion. The Fourth, Sixth, Eighth, and Tenth Circuits have held that a Rule 35(b) modification does not constitute a new judgment of conviction that restarts § 2255's statute of limitations clock.15 See Byers v. United States, 561 F.3d 832, 835 (8th Cir.2009) (holding that a Rule 35(b) modification does not constitute a "final judgment" and therefore does not reset the AEDPA time clock); Sanders, 247 F.3d at 142-44 & n. 2 ("It is beyond dispute that under § 3582, Rule 35 sentence modifications do not affect the finality of convictions for § 2255 purposes."); United States v. Chapman, 220 Fed.Appx. 827, 830 (10th Cir.2007) (noting that a Rule 35(b) modification does not reset the statute of limitations clock but acknowledging that even if it did, defendant's motion still would have exceeded the one-year limit); Reichert v. United States, 101 Fed.Appx. 13, 14 (6th Cir.2004) ("Under 18 U.S.C. § 3582(b), the defendant's original judgment of conviction remains the final judgment even if his sentence has been modified or reduced as the result of the government filing a Rule 35 motion.").

Finally, concluding that a Rule 35(b) modification does not reset the § 2255(f) limitations clock is consonant with Congress's overriding purpose in enacting AEDPA. Congress designed AEDPA "`to achieve finality in criminal cases, both federal and state.'" Jones v. United States, 304 F.3d 1035, 1039 (11th Cir.2002) (per curiam) (quoting Brackett v. United States, 270 F.3d 60, 69 (1st Cir.2001)). Accordingly, we give "strict interpretation" to the one-year statute of limitations to avoid "`creat[ing] a loophole which is contrary to the legislative intent of insuring a greater degree of finality.'" Id. (quoting Brackett, 270 F.3d at 69). To hold that a district court's Rule 35(b) modification to a sentence constitutes a new final judgment would create just such a loophole. Any Rule 35(b) modification of a defendant's sentence—no matter how far into the future—would allow the defendant to bring stale claims under § 2255. Put differently, so long as any possibility exists that the defendant might learn of information that would result in a Rule 35(b) reduction, a defendant's judgment of conviction would never become final.

B.

Murphy contends that our conclusion is inconsistent with this court's decision in Ferreira v. Secretary, the Department of Corrections, 494 F.3d 1286 (11th Cir.2007) ("Ferreira II"). In Ferreira II, after the Supreme Court summarily vacated our original decision, we held that 28 U.S.C. § 2244(d)(1), the one-year statute of limitations that governs the filing of habeas corpus petitions under 28 U.S.C. § 2254,16 began to run "when the judgment pursuant to which the petitioner is in custody, which is based on both the conviction and the sentence the petitioner is serving, is final." Id. at 1293. Murphy argues that a Rule 35(b) modification of a sentence constitutes a new sentence and therefore a new "judgment pursuant to which the petitioner is in custody." We disagree.

Ferreira II involved a state habeas petitioner who had been resentenced after being granted state post-conviction relief. The resentencing occurred after AEDPA's statute of limitations for the original judgment of conviction and sentence had run. Ferreira v. Sec'y, Dep't of Corr., 183 Fed. Appx. 885, 886 (11th Cir.2006) ("Ferreira I").17 Although Ferreira challenged only his underlying conviction, he argued that the statute of limitations should run from the date of resentencing. Id. At the time of Ferreira I, our precedent held that if the petitioner challenged both the underlying conviction and the subsequent resentencing, then the statute of limitations ran from the date the "resentencing judgment" became final, Walker v. Crosby, 341 F.3d 1240, 1246 (11th Cir.2003); if, however, the petitioner challenged only the underlying conviction, then the statute of limitations ran from the date the original judgment of conviction became final, Rainey v. Sec'y, Dep't of Corr., 443 F.3d 1323, 1325-26 (11th Cir.2006). Because Ferreira attacked only his underlying conviction, the Ferreira I court held that his petition was barred. Ferreira I, 183 Fed.Appx. at 886. The Supreme Court summarily vacated Ferreira I and remanded for reconsideration in light of Burton v. Stewart, 549 U.S. 147, 127 S.Ct. 793, 166 L.Ed.2d 628 (2007) (per curiam).

On reconsideration, we read Burton for the proposition that the writ and AEDPA are "specifically focused on the judgment which holds the petitioner in confinement."18 Ferreira II, 494 F.3d at 1293. Because Burton reaffirmed that a "judgment" means conviction and sentence, we concluded that the "judgment" to which AEDPA refers is the "underlying conviction and [the] most recent sentence that authorizes the petitioner's current detention."19 Id. at 1292 (emphasis added). Accordingly, we recognized that Burton effectively overruled Rainey, and held that when a petitioner is resentenced after AEDPA's one-year statute of limitations has expired for the original judgment of conviction and sentence, the judgment entered upon resentencing constitutes a new judgment holding the petitioner in confinement. A new judgment resets the statute of limitations clock and a petitioner may challenge both the underlying conviction and the resentencing. Id. at 1293.

In sum, we reasoned in Ferreira II that: (1) § 2244(d)(1)'s one-year statute of limitations starts to run from the date the judgment becomes final, (2) a judgment is defined as both the conviction and the sentence, and (3) therefore, when a defendant is resentenced, the defendant becomes confined under a new judgment from which a new one-year statute of limitations period starts to run.20 Taking this as his starting point, Murphy argues that any modification of a sentence results in a new judgment. We reject this argument because Ferreira II is distinguishable.

First, Ferreira II interpreted the term "judgment" in 28 U.S.C. § 2244(d)(1). Citing Burton, the court did so in the absence of a precise definition of "judgment" from Congress. See id. at 1292. Here, however, the question is how a Rule 35(b) sentence modification impacts the finality of the "judgment of conviction" specified in § 2255. In Rule 35(b), Congress created a special avenue whereby a district court may "modify" a sentence of imprisonment; in 18 U.S.C. § 3582(b), Congress specifically stated that taking that avenue does not affect the finality of the underlying judgment. Regardless of how the Supreme Court or prior panels of this court have construed the term "judgment" in § 2244(d) and the § 2254 context, we are not free to extend those decisions to the § 2255 context when doing so would flout Congress's plainly expressed intent. In short, we are not free to "replace the actual text" about how a Rule 35(b) modification affects the finality of a judgment of conviction with "speculation as to Congress' intent." Magwood v. Patterson, ___ U.S. ___, 130 S.Ct. 2788, at 2798, 177 L.Ed.2d 592 (2010); see also Sanders, 247 F.3d at 144 ("We are obligated to follow Congress' judgment on this matter and apply the plain text of the statute.").21

Second, apart from § 3582(b), Ferreira II is distinguishable because it dealt with a defendant who was resentenced after his sentence was declared invalid. See Ferreira II, 494 F.3d at 1288 (noting that Ferreira was resentenced after a state court granted his post-conviction motion to "correct" his sentence). When the corrected sentence replaced it, the new sentence together with the old conviction formed a new judgment. Rule 35(b) is altogether different.

Rule 35(b) authorizes a reduction in a defendant's prison sentence if and only if two conditions are met. First, the defendant must render substantial assistance to the Government in the investigation or prosecution of another person. Second, the Government must decide to file a Rule 35(b) motion. The Government has virtually unfettered discretion to determine whether the defendant rendered substantial assistance and whether to file the motion. See United States v. Nealy, 232 F.3d 825, 831 (11th Cir.2000) (stating that the government's Rule 35(b) decision can be questioned "only to the extent that the government ... exercise[d] that power, or fail[ed] to exercise that power, for an unconstitutional motive"). Even assuming the Government chooses to move for a Rule 35(b) reduction, the district court possesses extremely broad discretion to grant or deny the motion. See United States v. Manella, 86 F.3d 201, 203 (11th Cir.1996) (per curiam) (explaining that reducing a sentence under Rule 35 is a discretionary call from which "an appeal generally will not lie" unless the district court misconstrued its authority or made an error of law).

Accordingly, the Government's Rule 35(b) motion is merely a "plea[] for leniency," a matter of executive and judicial grace. Brown v. United States, 480 F.2d 1036, 1039 (5th Cir.1973).22 In fact, it is impossible for the "the validity of the underlying conviction, and, indeed, of the sentence itself" to be at issue in a Rule 35(b) proceeding.23 Id.; see also United States v. White, 251 Fed.Appx. 658, 659 (11th Cir.2007) ("Contrary to White's assertion, Rule 35(b), by its own terms, provides for a reduction of a sentence, not the vacating of a sentence and a resentencing."). If the validity of the underlying conviction or sentence cannot be at issue in a Rule 35(b) proceeding, it makes no sense to say that a Rule 35(b) reduction constitutes a genuine "resentencing" that gives rise to a new "judgment" that imprisons the § 2255 movant. See Berman v. United States, 302 U.S. 211, 212-14, 58 S.Ct. 164, 166, 82 L.Ed. 204 (1937) (holding that once a sentence is imposed, it is a valid final judgment until it is reversed or vacated). Instead, a defendant imprisoned by a sentence that has been reduced under Rule 35(b) is still serving the original, valid, and final judgment of conviction and sentence.24 See Ferreira II, 494 F.3d at 1292 (concluding that the relevant judgment for the purposes of § 2254 is "the one that places the petitioner in custody.").

III.

Because Congress has declared that a Rule 35(b) reduction of a sentence does not affect the finality of a judgment of conviction, and because a Rule 35(b) reduction does not constitute a resentencing where an old sentence is invalidated and replaced with a new one, Murphy's conviction became final on May 9, 2005. Accordingly, the district court's order rejecting Murphy's August 3, 2007, § 2255 motion as time-barred is

AFFIRMED.
