Time zone reference
Guam
Pacific/Guam is an IANA time-zone identifier currently displaying an offset of UTC+10:00 and the abbreviation ChST. Daylight-saving time is not active at the profile generation time. The next detected offset transition is not found within the next year. Civil-time rules can change after government announcements, and historical coverage is less complete before 1970; applications should use an updated tzdb release rather than hard-coded offsets.
