you should probably use
@strtotime
(same function but silences errors)
it's kind of a buggy function but invaluable for what it does.

Question
Convert times in PHP (add/substrct time)
I have times stored in a database like "9:30 am" or "10:00 pm" and I am trying to convert these times to GMT (I have the offset stored in a table) but am unsure of how I can convert these in PHP.
So I may have a time stored as "10:00 pm" stored in the database and the user is EST so I want to convert that time to GMT then take the GMT time of the meeting and add the offset of the user so that it returns a time in a smilar format.
So if I have a time in the database for a user stored as 11:00 am and for that user they are EST. They have a meeting with someone who is CST, I am trying to reach the outcome of their local time so that when they receive the email it has the time local to them.

Came up with my own solution not long after I posted my question but it works good.
$time = '11:00 am';
//Convert time to GMT
$originalOffset = str_replace("-", "+", "-5") . " hours";
$gmtTime = strtotime($originalOffset,
$gmtTime = strftime( "%I:%M %p",$gmtTime);
//Convert time to users time
$usersOffset = '-6 hours';
$prospectTime = strtotime($usersOffset, strtotime($gmtTime));
$prospectTime = strftime( "%I:%M %p",$prospectTime);
echo 'GMT: ' . $gmtTime . '<br/>Appointment for user: ' . $time . '<br>For prospect: ' . strtolower($prospectTime);

just use strtotime() to convert the database time to a unix timestamp and then add the GMT offset
as a hint, you might find it easier to store ALL times in the database in GMT. this way you'd only have one conversion (to the client's timezone) when you have to display a meeting.
