SST
Sakhalin Standard Time
Sakhalin Standard Time (SST) is Russia’s Far East gateway, following UTC+11:00 year-round on Sakhalin Island with no daylight saving switches. Teams stepping into SST work with a reliable +11 offset that makes late-morning calls from Sakhalin overlap neatly with European afternoons.

About SST
A fixed, year-round offset.
Sakhalin Standard Time (SST) is Russia’s Far East gateway, following UTC+11:00 year-round on Sakhalin Island with no daylight saving switches. Teams stepping into SST work with a reliable +11 offset that makes late-morning calls from Sakhalin overlap neatly with European afternoons.
IANA zones · the technical identifiers
The zone that resolve to SST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.
Where SST is used
One country.

Other zones at UTC+11:00 right now.
These named zones share SST's offset today. When daylight saving rules differ, they drift apart for part of the year.
Frequently asked questions
Common questions about SST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- What region uses SST in Russia?
- SST is used by Sakhalin Island, which follows Asia/Sakhalin and stays on UTC+11:00 all year.
- Does SST observe daylight saving?
- No. SST has no daylight saving transitions, so the +11 offset is constant and easy to plan against.
- When was the current +11 offset set for Asia/Sakhalin?
- Asia/Sakhalin has kept this '+11' setup since May 2021, and there are no pending transitions.
- How many clocks need to be tracked in this region?
- Just one member zone—Asia/Sakhalin—so SST scheduling rarely involves internal offsets or unexpected exceptions.
- What’s it like collaborating with someone in +11?
- Your +11 colleagues sit well into European business hours, but you’ll mostly connect with them early in your morning or late at night from the Americas.
- Is SST grouped with Vladivostok time?
- Not on this page. SST is a separate Russian region code at +11 and is distinct from Vladivostok or Magadan time.
- Why does Sakhalin stay on +11 all year?
- Russia abolished daylight saving in 2014, and Sakhalin settled permanently on +11 for consistency in energy, logistics, and transport planning.
