I mentioned this elsewhere in this thread, but abbreviations are not unique across timezones. The rules for timezones change based on locale, and if you have multiple zones with PST as an abbreviation, which one do you use? It has to be an explicit choice or it's almost certainly going to be wrong. There is no way to get America/Los_Angeles from PST without knowing the locale that the date and time is from.
