It is meaningless to talk about "whether DST is in effect or not"
without a specific time zone as context. The answer is "NO" if the
time zone is GMT. A specific time zone *offset* is not enough, as
the DST starting and ending dates may depend on what country is
involved. And the USA just messed up any programs with this info
hard-coded by changing the starting/ending dates for DST in 2007
and beyond. I am not sure it's been determined yet whether Canada
and Mexico will go along with the change or not.
