About UTC−8
UTC−8 is 8 hours behind Coordinated Universal Time: when it is noon UTC, it is 4:00 AM at UTC−8.
1 zone keeps UTC−8 all year, covering 1 country or territories: Pitcairn.
2 zones use it only in winter and move to UTC−7 in summer, for example Los Angeles and Tijuana.
6 zones reach it only in summer, from standard time UTC−9, for example Anchorage, Juneau and Metlakatla. So the set of places on UTC−8 changes twice a year.
For a fixed offset in software, tzdata provides Etc/GMT+8; note the inverted sign of these POSIX-style names.
Abbreviations for UTC−8: PST (Pacific Standard Time), AKDT (Alaska Daylight Time).
