This case took wing when the Air Line Pilots Association (ALPA), a labor organization, sued defendant-appellant Precision Valley Aviation, Inc. (Precision) to compel arbitration of a grievance initiated by the union on behalf of certain probationary employees (all pilots). The district court ordered Precision to arbitrate the dispute. Precision now seeks to test the substance of the district court’s order. We do not reach that destination: the absence of appellate jurisdiction defeats the main thrust of the appeal, and what remains does not require us to extend our flight much beyond takeoff.
I.
A Chronology
This appeal is enveloped in a jurisdictional fog. We attempt to clear the air by chronicling the events that frame the jurisdictional issue.
1. August 17, 1993: The district court, acting on a motion for summary judgment, entered a final judgment in ALPA’s favor on count 1 of its complaint. At the same time, the court dismissed count 2 of the complaint for want of subject matter jurisdiction. The second part of the court’s order is immaterial to this appeal.
2. August 30, 1993: Precision attempted to move for reconsideration, but failed to comply with an applicable local rule. 1 Consequently, the clerk of court refused to accept the defective pleading (which we shall refer to as the noncompliant motion) for filing.
3. August 31, 1993. The district court, acting at ALPA’s request, entered an amended judgment clarifying the original judgment. On the same date, Precision filed a notice of appeal.
4. September 1, 1993: The district court entered an “Order of Refusal of Pleading,” endorsing the clerk’s refusal to place the noncompliant motion on record.
5. September 9, 1993: Precision served a new motion for reconsideration of the August 17 judgment. This motion satisfied the requirements of the local rules.
6. September 10, 1993: Precision filed the September 9 motion in the clerk’s office. It also requested a stay of judgment pending appeal. On the same date, Precision withdrew its first notice of appeal.
7. September 22, 1993: The district court entered an order declining to reconsider the final judgment and denying Precision’s request for a stay. The court stated that a motion for reconsideration should have been served on or before August 27, and that Precision’s efforts were, therefore, untimely. The court erred in identifying the end date; taking into account the special directives of the Civil Rules, see Fed.R.Civ.P. 6(a) (explaining principles governing computation of periods of 10 days or less), the 10-day period for filing a motion to alter or amend the judgment, Fed.R.Civ.P. 59(e), did not expire until August 31.
8. October 7, 1993: Precision filed a motion for reconsideration of the September 22 order (having served the motion a day earlier). In this motion, Precision pointed out the court’s computational error and contended that the noncompliant motion met the applicable time constraints.
*223 9. October 12, 1993: Although acknowledging its computational error, the district court nevertheless remained steadfast and denied Precision’s October 7 motion. The court noted that the noncompliant motion did not conform to Local Rule 11(b) and was, therefore, a nullity. The September 9 motion also lacked force, as that motion was neither served nor filed within the requisite 10-day period.
10. October 13, 1993: The court entered a further judgment commemorating the October 12 order, as required by Fed. R.Civ.P. 58. See Fiore v. Washington County Comm. Mental Health Ctr.,960 F.2d 229 , 233 (1st Cir.1992) (en banc).
11. November 5, 1993: Precision filed its notice of appeal, seeking to challenge (a) the August 17 judgment, (b) the September 22 order, and (c) the October 13 judgment.

Analysis
A
In civil cases in which the United States is not a party, a notice of appeal must be filed within thirty days following the entry of final judgment.
See
Fed.R.App.P. 4(a)(1). The requirement for punctual filing of a notice of appeal is obligatory and jurisdictional.
See Browder v. Illinois Dep’t of Correction,
Appellant offers a variety of possible scenarios, all of which implicate Fed. R.Civ.P. 59(e). In terms, a motion to alter or amend a judgment, made under that rule, interrupts the running of the appeal period as long as it is “served not later than 10 days after entry of the judgment.” Thereafter, an order disposing of the motion restarts the appeal period.
See Feinstein,
This is not to say that a motion for reconsideration filed after the 10-day window closes is completely inutile. While such a motion will not extend the appeal period, the district court, so long as it still retains jurisdiction, may choose to grant the requested relief.
See Jusino v. Zayas,
B.
It is against this tightly woven backdrop that we turn to appellant’s asseverational array. Appellant’s central claim is that, whatever its deficiencies might have been, the noncompliant motion was a timely-filed Rule 59(e) motion and, therefore, tolled the appeal period in respect to the August 17 judgment. We do not agree.
This initiative depends on the significance of the admitted defect in the motion—the motion plainly did not satisfy the requirements of the local rules—and the supportability of the lower court’s response to it. Appellant attempts to shrug off the matter of noneompliance, contending, in effect, that Local Rule 11(b) is somewhat silly, and that the district court’s slavish adherence to it sanctifies “an empty formality.”
We think appellant presumes too much. Rules of procedure are vitally important in judges’ efforts to manage burgeoning caseloads with some semblance of efficiency. Within wide limits, it is for courts, not litigants, to decide what rules are desirable and how rigorously to enforce them.
See Maldonado-Denis v. Castillo-Rodriguez,
By like token, we do not discern any error in the court’s application of the rule. District courts enjoy broad latitude in administering local rules.
See United States v. Roberts,
In this instance, the local rules explicitly warn litigants that the court will “not accept any motions not in compliance with procedures outlined in [the local rules].” D.N.H.Loc.R. 11(a)(1). This provision, aposematic in and of itself, is reinforced by a further provision that clearly contemplates the striking of noncompliant pleadings.
See
D.N.H.Loc.R. 2(f).
5
Mindful of this profusion of red flags, we cannot say that the judge responded inappropriately to appellant’s breach of Local Rule 11(b).
See Clausen,
c.
Appellant’s next argument is ingenious, but unpersuasive. Although phrased in various ways, the argument amounts to a claim that the September 9 motion, see Chronology, supra at No. 5, somehow related back to the date of the noncompliant motion or served to reinstate that motion nunc pro tunc.
The short, dispositive answer to this claim is that the local rules do not accord a non-compliant motion any force or effect. To the contrary, the rules rather conspicuously convey the court’s intention to treat noncompli-ant motions as null and void. See D.N.H.Loe.R. 11(a)(1) (stating that the clerk of court shall refuse to accept noncompliant motions for filing); see also D.N.H.Loe.R. 2(f) (explaining that noncompliant documents are subject to being stricken).
If there is any lingering doubt as to this reading of the local rules—and we see no room for any such dubiety—it is dispelled by the instruction contained in the district court’s order of refusal, Chronology,
supra,
at No. 4, which stated: “When/if resubmitted, the [motion] should contain a recertification of service on opposing counsel/parties.” The order of refusal also discussed the possibility that resubmission of the motion might “bring the filing outside of a specific date as set by court rule.” In other words, the court made plain that the old motion was dead and that a new motion, having a new filing date, would be required. Since a district court’s plausible construction of its own local rule is entitled to considerable deference,
see, e.g., City of Waltham v. United States Postal Serv.,
To sum up, the noncompliant motion was a nullity. It follows inexorably that the September 9 motion did not relate back to the earlier motion or supplant it nunc pro tunc. Rather, the new motion had to be evaluated on its own merit, not as an extension of the noncompliant motion. So viewed, the September 9 motion cannot serve as a vehicle for restarting the appeal period because it was filed beyond the 10-day period stipulated in Rule 59(e).
D.
Appellant’s next attempt to reach the August 17 judgment smacks of trying to cram a square peg into a round hole. Precision posits that an appellate court may grant special dispensation from the temporal requirement for docketing a notice of appeal “where an appellant has filed a belated motion for reconsideration and relied on the district court’s statement that the motion was timely in forgoing the timeous filing of a notice of appeal.”
Feinstein,
There are two preconditions to the availability of the “unique circumstances” exception. First, the exception “applies only where a party has performed an act which, if properly done, would postpone the deadline for filing his appeal and has received specific assurance by a judicial officer that this act has been properly done.”
Osterneck v. Ernst & Whinney,
Appellant’s contrary claim has two prongs. One centers around the district court’s initial denial of the September 9 motion. See Chronology, supra, at No. 7. This prong is easily blunted. After all, the court ruled unequivocally that the motion was un *226 timely vis-a-vis the final judgment. The fact that the court made an erroneous calculation in the course of announcing its ruling was unfortunate—but, given the denial of the motion, the bevue could not in any way have lulled appellant into a false sense of security regarding filing deadlines.
The remaining prong of appellant’s claim focuses on Precision’s ostensible belief that, when the district court rejected the noncom-pliant motion, it (Precision) could refile the motion nunc pro tunc after paying belated obeisance to Local Rule 11(b). But if appellant harbored this belief, it was wishful thinking—not premised on anything that the district court did or said. Indeed, the order of refusal expressly stated that “if the resubmission of said pleading will bring the filing outside of a specific date as set by court rule or court order, a motion for extension must accompany the refiling.”
That effectively ends the matter. Where a party claims to have relied to its detriment on a trial judge’s statement or action, it can derive no benefit unless its reliance is objectively reasonable.
See Feinstein,
Appellant’s remaining attempts to reach the underlying judgment are meritless and do not require discussion. We lack jurisdiction to review the August 17 judgment.
E.
Appellant also contends that the district court erred in denying its two later motions for reconsideration.
See
Chronology,
supra,
at Nos. 5-6, 8. Although the notice of appeal is timely as to these rulings,
6
it does not serve to reopen the expired appeal period vis-a-vis the underlying judgment.
See Rodriguez-Antuna,
As a practical matter, the October 13 judgment adds very little to the mix. That judgment memorializes the district court’s denial of the October 6 motion for reconsideration. To the extent that the motion successfully sought correction of a misstatement made by the district court in the September 22 order, see Chronology, supra, at No. 7, appellant prevailed, and cannot appeal. To the extent that the October 6 motion unsuccessfully sought a change in the bottom-line disposition of the case, the court’s rejection of it stands on a par with the court’s rejection of the September 9 motion for reconsideration, memorialized in the September 22 order. Accordingly, we discuss only the September motion and order—but we do so on the express understanding that our comments apply with undiminished force to what transpired in October.
The September 9 motion sought reconsideration of the underlying judgment. Under First Circuit precedent, an untimely Rule 59(e) motion may be dismissed summarily by the trial court.
See, e.g., Rodriguez-Antuna,
*227
In this instance, the lower court chose the former option. Even had the court chosen the latter option, however, an equally unhappy fate would have awaited the movant. In the last analysis, the court of appeals will overturn a district court’s denial of a motion for reconsideration only if the record evinces a clear abuse of discretion.
See Fragoso v. Lopez,
In its motion, Precision asked that the order to compel arbitration be reexamined for two reasons. First, it asserted that the court reached an erroneous legal result, pure and simple. Insofar as the motion was predicated on this ground, the court appropriately rejected it: a trial court, having considered the parties’ arguments and ruled on them, is under no obligation to repastinate well-ploughed soil simply because an unsuccessful litigant balks at taking “no” for an answer.
See National Metal Finishing Co. v. BarclaysAmerican/Commercial, Inc.,
Appellant also requested reconsideration in light of a ruling handed down by the National Mediation Board (NMB) on August 11, 1993, while ALPA’s motion for summary judgment was pending in the district court. This constituted new matter. The issue before the NMB concerned the representation of phots employed by Precision and by an affiliated airline. The NMB determined that the two airlines comprised a “single transportation system” for collective bargaining purposes under the Railway Labor Act, 45 U.S.C. §§ 151-188 (1988), and ordered a representation election. Seizing on this development, appellant’s motion posited that arbitrating the grievance underlying this case with a representation election in the offing would infringe upon the jurisdiction of the NMB.
This contention comprises more bleat than wool. Precision neglects to mention that the NMB’s order specifically provides that “[pjending resolution of this representation dispute, ALPA’s certification [as the collective bargaining representative for Precision’s pilots] remains in effect.” Given the untimeliness of appellant’s motion and the NMB’s clear statement anent ALPA’s representational authority, we find no hint of abused discretion in the district court’s order refusing reconsideration.
III.
Conclusion
We need go no further. 7 When Precision elected to disregard Local Rule 11(b), it flew headlong into unfriendly skies. In the aftermath of this pilot error, we lack appellate jurisdiction to review the underlying judgment on the merits. Substantively, then, our scrutiny must be confined to the denial of two post-judgment motions. On that circumscribed basis, Precision’s appeal stalls.
Affirmed.
Notes
. District courts are empowered to make local rules for the administration of the court docket.
See
Fed.R.Civ.P. 83. The District of New Hampshire has promulgated a set of local rules. One such rule provides that, with regard to most motions, "[t]he moving party shall certify to the court that he has made a good faith attempt to obtain concurrence in the relief sought.” D.N.H.Loc.R. 11(b). This rule applies foursquare to post-judgment motions (such as are at issue in this case).
See Clausen v. Sea-3, Inc.,
. The parties agree that final judgment entered on August 17, 1993. Though the district court entered an amended judgment on August 31, 1993,
see
Chronology,
supra,
at No. 3, the amendment served strictly as a means of clarification and did not alter the parties’ substantive rights under the preexisting judgment. The settled rule is that the non-substantive revision of a previously entered judgment does not restart or otherwise affect the period within which appellate review must be sought.
See FTC v. Minneapolis-Honeywell Co.,
. The timeliness of a Rule 59(e) motion is determined by the date of service, not the date of filing.
See Perez-Perez
v.
Popular Leasing Rental, Inc.,
. This court has recently upheld the validity of D.N.H.Loc.R. 11(b),
see Clausen v. Sea-3, Inc.,
. Appellant senses a possible contradiction in the district’s local rules. We perceive no inconsistency. While Local Rule 2(f) instructs that "[d]ocuments which fail to comply with the provisions of these rules shall be filed by the clerk, subject to being stricken by the court,” Local Rule 11(a)(1) instructs that ”[t]he Clerk shall not accept any motions not in compliance with procedures outlined in these Rules.” The latter rule is narrowly tailored and relates specifically to motions. Hence, it governs in cases involving nonconforming motions. See generally 2B Norman J. Singer, Sutherland Statutory Construction § 51.05 (5th ed. 1992) (explaining that, when two statutes are in seeming conflict, the more specific statute ordinarily controls).
. The district court denied the September 9 motion by order entered September 22, 1993. See Chronology, supra, at No. 7. We assume arguen-do, favorably to appellant, that the ensuing motion for reconsideration, filed on October 6, see id. at No. 8, suspended the running of the appeal period with respect to a possible appeal of the September 22 order. See Fed.R.Civ.P. 59(e); Fed.R.App.P. 4(a)(1). On this assumption, the appeal period began to run afresh on October 13, following the denial of appellant’s October 6 motion. The notice of appeal was filed within thirty days of this date. See Chronology, supra, at No. 11.
. The current version of Fed.R.Civ.P. 5(e) provides, inter alia, that "[t]he clerk shall not refuse to accept for filing any paper presented for that purpose solely because it is not presented in proper form as required by these rules or any local rules or practices.” Appellant neither cited this rule nor relied on it in any way and has, therefore, waived any potential benefit which might accrue from it. For this reason, we do not refer to the rule in the body of this opinion. But we note that, in all events, the clerk’s refusal to accept the noncompliant motion for filing in this case was backed by the judge’s specific order, see Chronology, supra, at No. 4, leaving the record in essentially the same posture as though the motion had been received and then stricken. Any error was, therefore, harmless.
