> Looking at the difference between localtime() and gmtime() will tell me the offset between local time and GMT, but it won't tell me what time zone I am in.  For example, in the summer in Phoenix the offset is the same as the offset in L.A., but in the winter the Phoenix offset is the same as the Denver offset.  So if the offset is seven hours, how do I know if I am in Denver, Phoenix or L.A?

Phoenix is in neither PST nor MST - it is in its own special time zone.  Other areas of the world (e.g. southern Indiana) are just as weird.
