Who keeps UTC−10:00

Three zones, all of them permanent.

None of the zones keeping UTC−10:00 right now observe daylight saving — what you see here in June is what you get in December. One neighbour, Adak, is based here but is spending the season a rung away.

About this offset

One rung, three flags.

UTC−10:00 is kept by 3 zones across United States, Cook Islands and French Polynesia. All of its resident zones keep it permanently — no daylight saving, no seasonal drift. One zone based here is currently away on the next rung.

Its one notable trick: UTC−10:00 shares its clock face with UTC+14:00. Kiritimati, a full day ahead, shows the same time on a different date — the two ends of the offset ladder meeting in the middle of the Pacific.

What time is it at UTC−10:00 right now?
UTC−10:00 is always exactly 10 hours behind Coordinated Universal Time, every day of the year. The clock at the top of this page shows its current time live — in military usage this offset is zone W (Whiskey).
Which countries use UTC−10:00?
Three territories keep UTC−10:00 year-round: United States (Pacific/Honolulu), Cook Islands (Pacific/Rarotonga), French Polynesia (Pacific/Tahiti).
Is Papeetē always on UTC−10:00?
Yes. Papeetē does not observe daylight saving time, so it stays at UTC−10:00 every day of the year.
What's the difference between UTC−10:00 and TAHITI?
UTC−10:00 is the numeric offset; TAHITI (Tahiti Time) is one named time zone that keeps it. Other zones can share the offset while following entirely different rules and history — same clock, different identity.
