When a run stops on a usage limit, the composer banner printed the reset time with toLocaleString(). It ignored Settings > Time format, so with 24-hour selected it read "Resets 10/21/2026, 5:30:00 PM" while the timeline row right above it read "Retry after tomorrow at 17:30".

Takeover of #22112 by @only21mil. Their commits are kept with their authorship. The banner now uses formatUpcomingTimestamp with the client's timestampFormat, the same helper and setting the timeline row uses. I changed the test to assert fixed strings instead of comparing against formatShortTimestamp, which copied the implementation, and added a case for a reset tomorrow.

This covers web and desktop (desktop renders the same component). Mobile does not render this banner and is not changed. The banner label does not tick over at midnight on its own. That is the same as the timeline row (TimelineWorkEntryRow.tsx, which also uses the default Date.now()), and the label updates on the next render.

Before	After

Screenshots are component renders in headless Chromium with Time format set to 24-hour, not a full app run.

Proof: UsageLimitRecoveryBanner.test.tsx fails 3 of 3 with main's banner code (for example, expected "Resets 17:30", received "Resets 10/20/2026, 5:30:00 PM") and passes 3 of 3 here. It also passes with TZ=UTC, TZ=Pacific/Auckland LANG=de_DE.UTF-8, and TZ=America/Chicago LANG=en_US.UTF-8. vp run check:changed passes (format, lint, knip, typecheck, tests). I did not run the full app or test the "locale" Time format with a fixed string, because its output depends on the host locale.

If #21952 merges first, its banner test fixture needs the new timestampFormat prop.

Approvability

Verdict: Approved at e7e5b1f

Macroscope's review found this PR approvable — This is a narrowly scoped presentation fix that routes the existing time-format preference through the shared timestamp formatter. It changes only the usage-limit banner’s displayed reset text, with tests covering 12-hour, 24-hour, and tomorrow cases.

The formatting change appears mergeable, but add a default-locale assertion so a regression in the format most users receive is detected.

Add an assertion for the default locale format.

Every test case passes "12-hour" or "24-hour". Since settings default to "locale", a regression limited to that format could leave these assertions green. Add a locale case that checks its formatted reset label.
