Good point Stace, 

Not all places have  daylight savings, and they dont all change on the
same day the USA does.   And south of the equator, they change in the
opposite direction to the USA.

The closer a place is to the equator,  the less is the difference in
daylight hours between the equinoxes, and therefore there is less need
for daylight savings time changes.   In fact in most tropical zones
they dont even have four seasons.    Then as you get closer to the
poles, the difference in daylight hours is so huge that an hour's
daylight savings is hardly relevant.

In Australia, for example,  Queensland in the north, most of which is
in the tropics, has no daylight savings change.   The more southern
states, in more temperate zones and heading down towards the antarctic
have a need for daylight savings.  But political pressures often make
the states change the dates they change on.(e.g. the NSW government
changed our dates in 2000 to suit the TV channels broadcasting the
Olympics).

So these factors add up to meaning that daylight savings is on (or
not) in different parts of the world at different times, and in
different directions.   If you want to allow for daylight savings,
you'll need to do some research into which states in which countries
change, and when.   Then you'll need to keep your research updated.

Perhaps there's a database somewhere.  Does anyone know?

Or instead just stick to GMT and let the users do their own adjustments.
