A big revelation for me in solving so much timezone insanity came from realising that timezones should be expressed as locations rather than zones.

Avoid general terms like "Pacific Standard Time" and stick to location-specific ones like: "Vancouver/Canada". The latter is how people expect their time to work, and correctly handles whatever quirky choices jurisdictions choose to do with their time.

In my experience, all worthy date/time libraries use time zone IDs from the "tz database". Ref: https://en.wikipedia.org/wiki/Tz_database

Searching the list here: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

I cannot find an entry for "Pacific Standard Time" nor "Vancouver/Canada", but I can see: "America/Vancouver".

The rule of thumb is: Use UTC to record when things happened (e.g. logging), use local time + timezone name (e.g. `Europe/London`) to schedule things for the future (e.g. meetings).
