I think you might read this before:
http://php.net/manual/en/function.date.php
it has list of letters that represent a format.
But to answer your question, yes if you used strtotime() function plus you also need to used this
http://www.php.net/manual/en/timezones.php
Here is an link of how this work altogether:

@lastmitch thank you for the reply, and yes im using php's list of supported timezone, by using PHP's date_default_timezone_set, my only concern is the DST. example
date_default_timezone_set('America/Los_Angeles');
so it automaticaly computes for DST? i don't have to manually trap it? to add 1 hour on DST enabled month? and btw thanks for the link, ill read your 3rd link :D

@lastmitch thanks for the link, i think you are right, based on the article
php > $tz = new DateTimeZone("America/New_York");
php > $dt->setTimezone($tz);
php > print $dt->gt;format("r");

Notice the -0500 offset for the month of December. If you change the the time value to a summer date, such as July 1, you’ll see it is aware of Daylight Savings Time (EDT)
php > $tz = new DateTimeZone("America/New_York");
php > $july = new DateTime("7/1/2011");
php > $july->setTimezone($tz);
php > print $july->>format("r");
