About JST

Japan Standard Time (JST) is UTC+9. It is used in all of Japan, with no daylight saving.

Japan Standard Time is UTC+9 for the whole country and has had no daylight saving since 1951, when the occupation-era experiment was abandoned. Proposals to reintroduce it, most recently before the 2020 Olympics, have failed each time. The offset is shared with South Korea, so Tokyo and Seoul never differ by even a minute.

About MMT

Myanmar Time (MMT) is UTC+6:30. It is used in Myanmar, all year.

Myanmar Time is UTC+6:30, another of the half-hour zones and one of only a handful in Asia. It has no daylight saving. The same offset is used by the Cocos Islands, which is the only other place on it, so a UTC+6:30 timestamp is almost always Myanmar.

Does this gap change with the seasons?

Neither JST nor MMT shifts with the seasons, so this 2.5-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.

This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
