What if a time zone is specified together with the date/time value? For instance, is there any function that call whether "2007-11-04 01:30 PST" is DST?
Sorry, no; in general that's not possible, as in some locations the same abbreviation is used for both standard and daylight time.
Not to mention, by PST do you mean Pacific Standard time or Pitcairn Standard Time? The short abbreviations are now where near unique distinguishers. -Bennett
