About Lord Howe Standard Time (LHST)
LHST stands for Lord Howe Standard Time. Its exact offset is UTC+10, which means local time in LHST is 10 hours ahead of Coordinated Universal Time.
Lord Howe Standard Time does not observe DST and has no counterpart. That makes LHST a fixed standard-time abbreviation in this context, which is useful for people who want a stable reference when comparing schedules, planning calls, or documenting timestamps.
The same UTC offset is also used by the abbreviations ACDT and ACT. When comparing abbreviations, this matters because two time labels can share the same UTC offset while still being written differently in calendars, schedules, or software interfaces.
LHST and Daylight Saving Time
LHST does not observe daylight saving time. There is no seasonal switch, no daylight version of the abbreviation, and no counterpart that replaces it during another part of the year.
Because there is no DST change for LHST, the offset remains UTC+10 throughout the year. That consistency is useful for recurring coordination, since the LHST side of a schedule stays fixed even when other time zones may shift their clocks seasonally.
