Common questions
What is UTC in JST?
JST is 9 hours ahead of UTC today: noon in UTC is 21:00 in JST.
Is UTC the same all year?
UTC refers to the offset used by UTC. Where that zone observes daylight saving, the letters change with it, which is why this site stores the identifier and not the abbreviation.
When can UTC and JST meet?
They do not overlap during working hours. 08:00–09:00 your time (17:00 there) is the cheapest compromise.
