I think it's important to mention with the DateTime class that if you're trying to create a system that should store UNIX timestamps in UTC/GMT, and then convert them to a desired custom time-zone when they need to be displayed, using the following code is a good idea:

<?php
date_default_timezone_set
('UTC');
?>

Even if you use something like:

<?php
$date
->setTimezone( new DateTimeZone('UTC') );
?>

... before you store the value, it doesn't seem to work because PHP is already trying to convert it to the default timezone.

We can also get the submitted datetime (e.g. 2009-11-06 07:03:41) using the following:

<?php
$DateOfRequest
= date("Y-m-d H:i:s", strtotime($_REQUEST["DateOfRequest"]));
?>

Or another good example of getting DateTime:

<?php
$DateOfRequest
= date("Y-m-d H:i:s", mktime($_REQUEST["Hour"],$_REQUEST["Min"],$_REQUEST
["Sec"],$_REQUEST["Month"],$_REQUEST["Day"],$_REQUEST["Year"]));           
?>

Should you want to convert between HH:MM:SS and plain seconds like in MySQL, these functions should do the trick:

<?php
function time_to_sec($time) {
   
$hours = substr($time, 0, -6);
   
$minutes = substr($time, -5, 2);
   
$seconds = substr($time, -2);

    return
$hours * 3600 + $minutes * 60 + $seconds;
}

function
sec_to_time($seconds) {
   
$hours = floor($seconds / 3600);
   
$minutes = floor($seconds % 3600 / 60);
   
$seconds = $seconds % 60;

    return
sprintf("%d:%02d:%02d", $hours, $minutes, $seconds);
}
?>
