About UTC−3:30
UTC−3:30 is 3 hours 30 minutes behind Coordinated Universal Time: when it is noon UTC, it is 8:30 AM at UTC−3:30.
No zone keeps UTC−3:30 all year: it is only used as a winter (standard) time by zones that move to summer time.
1 zone uses it only in winter and moves to UTC−2:30 in summer, for example St. John's.
Offsets with half hours are a minority: of the 39 offsets in use, 13 are not whole hours. Countries usually choose one to put a single clock between two whole-hour zones, close to the sun in the middle of their territory.
Abbreviations for UTC−3:30: NST (Newfoundland Standard Time).
