Frequently asked questions
Common questions about TOMSKT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Which time zone uses Tomsk Time?
- Tomsk Time applies to Asia/Tomsk, covering the Tomsk region of Russia.
- Does Tomsk Time observe daylight saving?
- No. Since May 29, 2016, the region has remained on UTC+07:00 permanently, with no daylight saving transitions.
- How many time zones belong to TOMSKT?
- TOMSKT includes a single member zone: Asia/Tomsk.
- What was the last daylight saving transition in Tomsk?
- The most recent change occurred on May 29, 2016, when the region switched to permanent UTC+07:00, ending seasonal adjustments.
- Can I rely on Tomsk's offset to stay the same throughout the year?
- Yes. Today the representative zone shows the standard offset matching its current offset, so you can plan across months without worrying about clock shifts.
- Why do platforms display the abbreviation '+07' instead of a traditional acronym?
- Because Russia restructured its time zones and abandoned DST, many services label the literal UTC+07:00 offset as '+07' rather than a legacy acronym.
- What are some neighboring time zones Tomsk Time relates to?
- Tomsk sits between its historic daylight saving offset of UTC+07:00 and UTC+08:00 used by nearby regions, but since 2016 both standard and effective offsets align at UTC+07:00.
- Is there another region in Russia using the same offset?
- Yes. Omsk Time also uses UTC+07:00, so coordinating with Omsk-based colleagues requires no time difference adjustments, even though they fall under a different regional code.
- What should I do if I see 'unknown' for the next transition?
- Plan as if the offset will remain UTC+07:00 indefinitely, because no future daylight saving transitions are expected for Tomsk Time based on the region's recent history.
