Argentina Time
America/Argentina/Buenos_Aires is currently on UTC-03:00 (UTC-03:00). That is not ART — this page is named for the abbreviation people search for, and tells you the truth about which one is actually in force.
no clock change scheduled — this zone is fixed at UTC-03:00
Argentina Time is UTC-3 with no daylight saving since 2009, and the whole country runs one clock despite spanning enough longitude for three. Same offset as Brazil's BRT, different rule history.
Greenwich Mean Time
Etc/GMT is on GMT (UTC+00:00).
no clock change scheduled — 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.
