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.
Daylight saving right now
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.
Brasília Time
America/Sao_Paulo is on UTC-03:00 (UTC-03:00).
no clock change scheduled — fixed at UTC-03:00
Brasília Time is UTC-3. Brazil abolished daylight saving in 2019, so the offset no longer moves — a rule change many stale converters still get wrong.
