Getting a timezone's offset and other data at a specified point in time (now, for example) using the new PHP5.3 parameters:





<?php


$theTime = time(); # specific date/time we're checking, in epoch seconds.





$tz = new DateTimeZone('America/Los_Angeles');


$transition = $tz-getTransitions($theTime,$theTime);





# only one array should be returned into $transition. Now get the data:


$offset = $transition[0]['offset'];


$abbr = $transition[0]['abbr'];


?>





Before PHP5.3, you'd have to loop through all of the Transitions up until the current point in time, which would be a very inefficient process.
