SST
Sakhalin Standard Time
Sakhalin Standard Time (SST) is used in Russia's Sakhalin Island — the country's largest island, located just north of Japan. This remote timezone keeps a steady UTC+11:00 offset year-round with no daylight saving shifts, making scheduling predictably simple for the region’s tight-knit communities.

About SST
A fixed, year-round offset.
Sakhalin Standard Time (SST) is used in Russia's Sakhalin Island — the country's largest island, located just north of Japan. This remote timezone keeps a steady UTC+11:00 offset year-round with no daylight saving shifts, making scheduling predictably simple for the region’s tight-knit communities.
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

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 does SST stand for?
- SST stands for Sakhalin Standard Time, which follows a fixed UTC+11:00 offset.
- Is Sakhalin Standard Time adjusted for daylight saving?
- No, this region does not observe daylight saving time, so the UTC+11:00 offset stays the same throughout the year.
- Which areas use Sakhalin Standard Time?
- Sakhalin Island and the surrounding areas of Russia's Sakhalin region use this time zone.
- How does SST compare to Moscow Standard Time?
- SST is 8 hours ahead of Moscow Standard Time (UTC+3:00), which can make real-time meetings feel almost like calling into the future from Moscow’s perspective.
- When did Sakhalin fix its clocks at UTC+11:00?
- The region settled on the current UTC+11:00 offset on March 27, 2016, and has kept it unchanged ever since.
- Does SST’s lack of DST simplify planning?
- Yes. Because the offset never changes, you don’t need to track seasonal clock shifts when working between Sakhalin and other regions.
- Is Sakhalin the only place at UTC+11:00 in Russia?
- No, other Russian territories like Magadan and parts of the Kuril Islands share UTC+11:00, but Sakhalin is the only zone in Sakhalin Standard Time.
