//Server time Is Current Time of various timezone like(America/Chicago,America/Denver..)
$ServerTime   = 12:55:00;
//Scheduletime is coming from database
$ScheduleTime = 14:45:00;

$ExactTime    = ($Currenttime - $ServerTime) + $ScheduleTime

?>

Answer 1

You should use the DateTime class for this:

$Currenttime  = DateTime::createFromFormat('H:i:s', "12:40:00");
$ServerTime   = DateTime::createFromFormat('H:i:s', "12:55:00");
$ScheduleTime = DateTime::createFromFormat('H:i:s', "14:45:00");

$ExactTime    = $ScheduleTime->add($Currenttime->diff($ServerTime));
