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. :-)
