I neglected to include the solution in my last post for using strtotime()
with date-time data stored in GMT. Append the string "GMT" to all of your
datetimes pulled from MySQL or other database that store date-times in the
format "yyyy-mm-dd hh:ii:ss" just prior to converting them to a unix
timestamp with strtotime(). This will ensure you get a valid GMT result
for times during daylight savings.
EXAMPLE:
<?php
$date_time1 = strtotime("2004-04-04 02:00:00"); // returns bad value -1
due to DST
$date_time2 = strtotime("2004-04-04 02:00:00 GMT"); // works great!
?>
