Description: Convert the October 17, 2026 Codex limit reset announcement into UTC and Japan time, understand PST versus PDT, and distinguish an instant reset from a banked one.
Tibo announced “Day 13/ Le limit reset” on October 17, 2026 Pacific time, then added that it would be “Landing sometime today by EOD PST.” For a Codex user watching an empty allowance, the natural response is: what hour does that actually mean?
If end of day means 11:59 p.m. on October 17, the cutoff is October 18 at 06:59 UTC under PDT, or 07:59 UTC if PST is interpreted literally. In Japan, that is 3:59 p.m. or 4:59 p.m. JST. Neither is a promised launch minute: “sometime today” means it could land sooner.
One announcement, two Pacific clocks
California is observing PDT (UTC−7) on October 17, 2026. It does not switch back to PST (UTC−8) until November 1. People often say “PST” informally when they simply mean Pacific time. Yet Tibo actually typed PST, so the one-hour ambiguity is worth preserving. The later window is the conservative interpretation.
Will everyone get it immediately?
This is Day 13 of a 28-day Codex/Work challenge that promises a meaningful improvement or a full reset each day. The reply asking whether the reset was “banked or instant” gets straight to the practical question.
OpenAI calls a banked reset a one-time refresh eligible accounts can keep until they choose to apply it. An automatic/global reset applies directly to eligible usage limits. The short post does not specify the type, eligibility, or rollout completion. Check Codex Settings → Usage and later announcements before assuming your limit has already changed.
The calendar is trolling you
Someone in Japan sees “today” just after 1 a.m. and expects relief soon. But “today” in California continues through the next afternoon in Japan. You can sleep, wake up and finish lunch while a different continent is still working through yesterday.
So the sensible answer is by around 16:00 JST if PDT was intended, or around 17:00 if PST was literal. The reset may speed up your workflow; sadly, it cannot speed up the Earth's rotation.
