About KST
Korea Standard Time (KST) is UTC+9. It is used in South Korea, with no daylight saving.
Korea Standard Time is UTC+9, the same as Japan, and South Korea has had no daylight saving since 1988 when it was used for the Seoul Olympics. The two Koreas briefly differed: the North moved to UTC+8:30 in 2015 and returned to UTC+9 in 2018, which is the only time in modern history the peninsula ran on two clocks.
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 KST 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.
Frequently asked questions

Is MMT ahead of KST?
MMT is 2 hours 30 minutes behind KST.
Which time zone does this use?
KST is UTC+9 and MMT is UTC+6:30. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
