I think that it is better to use unixtimestamps and if you save them to a
RDBMS then save according to GMT. When retrieving use timezone to convert to
your local time -
ex

define('MY_TIMEZONE',-2);
list($time) = mysql_fetch_array(mysql_query('select tstamp from table where
user='.$user_id.';'));
$tt_ar = explode(':',gmstrftime('%H:%M:%S:%m:%d:%Y',$time));
$local_time = gmmktime($tt_ar[0]+MY_TIMEZONE, $tt_ar[1],
$tt_ar[2],$tt_ar[3],$tt_ar[4],$tt_ar[5]);

Regards,
Andrey
