I think you are missing a point here: time zones don't have DST.

There are two kinds of time zones: those with a fixed offset, which are easy to deal with, and what I would call "geographical" time zones, which map to one of two time zones depending on whether daylight savings is in effect. EDT, EST, MDT, MST, etc. are time zones with fixed offsets. "US/Eastern" and "America/New_York" are geographical time zones. Nearly every desktop computer in the world is set to a geographical rather than fixed time zone.

That's my understanding, anyway. I wouldn't mind being wrong, since it would make time zone manipulations oh-so-much simpler. :-)
