IANA zones · the technical identifiers
The zone that resolve to TST.
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.

- Does Turkmenistan observe daylight saving time?
- No. Turkmenistan Standard Time stays at UTC+05:00 all year, so there’s no need to adjust clocks for DST.
- Which zone represents Turkmenistan Standard Time?
- Ashgabat, the capital, is the representative city; all of Turkmenistan uses one offset, UTC+05:00.
- When did the current offset become effective?
- Turkmenistan has used UTC+05:00 since January 19, 1992, according to the official transition records.
- Do any member countries in this region observe DST?
- No. Turkmenistan is the only country on Turkmenistan Standard Time, and it does not observe daylight saving time.
