PHP Convert GMT time to local time

Get user timezone offset(ex. Timezone offset for nepal +5:45)

$userTzOffset = +5:45
$gmtDateTime = "2011-03-10 9:00"
$osts = explode(":",$userTzOffset);
$sec = ($osts[0] * 60 * 60) + $osts[1] * 60 ;
$gmtTimeStamp = strtotime($gmtDateTime, time()) + $sec;
$dt = date('Y-m-d::H:i:s',$gmtTimeStamp);

echo $dt;

Hope this will help someone.
