Conversion runs in your browser against the same IANA rules the server uses, so it keeps working offline and nothing you type is sent anywhere.

Greenwich Mean Time
Etc/GMT is currently on GMT (UTC+00:00).
no clock change scheduled — this zone is fixed at UTC+00:00
GMT is UTC+0 and never shifts. The UK observes GMT in winter only — in summer it is on BST (UTC+1), so "GMT" on a British invite dated in July usually means BST.
Japan Standard Time
Asia/Tokyo is on JST (UTC+09:00).
no clock change scheduled — fixed at UTC+09:00
Japan Standard Time is UTC+9 with no daylight saving — Japan has not observed DST since 1951, so the offset is safe to hard-code.
Best time to call green = 09:00–18:00 on both sides
No overlap inside a 09:00–18:00 day on both sides. Someone has to take an early or late slot — the table below shows exactly which hours are least bad.
