Pitcairn Standard Time shares the same UTC-8 offset as the abbreviations AKDT, PT, and U.

PST and Daylight Saving Time
Pitcairn Standard Time is the standard-time form, and its daylight saving counterpart is PDT. In real scheduling workflows, that means a timestamp marked PST identifies the UTC-8 standard-time offset, while PDT is the label used when daylight saving time is in effect.
Because PST is specifically the standard-time abbreviation, it does not itself represent the daylight saving period. When users ask when PST changes, the key point is that the abbreviation changes from Pitcairn Standard Time to PDT during the daylight saving portion of the cycle, so meeting labels, calendar exports, and shared links should be checked for the correct abbreviation before sending them to clients or teammates.
