About UTC−9
UTC−9 is 9 hours behind Coordinated Universal Time: when it is noon UTC, it is 3:00 AM at UTC−9.
1 zone keeps UTC−9 all year, covering 1 country or territories: French Polynesia.
6 zones use it only in winter and move to UTC−8 in summer, for example Anchorage, Juneau and Metlakatla.
1 zone reaches it only in summer, from standard time UTC−10, for example Adak. So the set of places on UTC−9 changes twice a year.
For a fixed offset in software, tzdata provides Etc/GMT+9; note the inverted sign of these POSIX-style names.
Abbreviations for UTC−9: AKST (Alaska Standard Time), HDT (Hawaii-Aleutian Daylight Time), HADT (Hawaii-Aleutian Daylight Time (old abbreviation)).

Fixed offsets only, so the table holds on any date; a city that observes daylight saving time is an hour later than its standard column in summer.
