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. One could do a reasonable job in most cases, as in the other problems you mentioned; it shouldn't be that hard, but the functions aren't there now.
