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 PKT

Pakistan Standard Time (PKT) is UTC+5. It is used in Pakistan, all year.

Pakistan Standard Time is UTC+5 and does not change through the year — daylight saving has been tried twice and abandoned twice. It sits half an hour behind India, which is the only pair of neighbouring countries in the region separated by a half-hour step rather than a whole one, and a common source of missed calls across that border.

Does this gap change with the seasons?

Neither JST nor PKT shifts with the seasons, so this 4-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.
