About Buenos Aires's time zone
Argentina observed daylight saving time intermittently through the 20th century before abolishing it for good in 2009, settling on a fixed UTC-3 offset year-round. That offset sits noticeably ahead of true solar time for Buenos Aires' longitude — a leftover of earlier DST periods that were never reversed.
