Here are some examples of date formatting in PHP.
<?php
/* Today is 2011-01-15T09:43:14+00:00 */
/* Common date formats*/
// ISO 8601 format
print date("c")."<br/>";
// January 15, 2011, 9:43am
print date("F j, Y, g:ia")."<br/>";
// 01.15.11
print date("m.d.y")."<br/>";
// 2011 Jan 15th
print date("Y M jS")."<br/>";
// 15, 1, 2011
print date("j, n, Y")."<br/>";
// 09:43:14
print date("H:i:s")."<br/>";
// 20110115
print date("Ymd")."<br/>";
// 20110117
print date("Ymd", strtotime("2 day"))."<br/>";
// 20101215
print date("Ymd", strtotime("-1 month"))."<br/>";
/* Set default time zone */
/* Hong Kong */
date_default_timezone_set("Asia/Hong_Kong");
// 2011-01-15T17:43:14+08:00
print date("c")."<br/>";
/* Create a date for Athens time zone */
$timezone = new DateTimeZone("Europe/Athens");
$date = new DateTime();
$date->setTimezone($timezone);
// 2011-01-15T11:43:14+02:00
print $date->format("c")."<br/>";
?>
Done =)
