Completed tom's DateTime for PHP 5.1 (and possibly earlier)
Still not perfect, still no timezone handling, but added minimal support for DateTime::setTime(),
DateTime::setDate(), DateTime::add(), Datetime::sub(), and DateInterval::__construct().
<?php
if (!class_exists('DateTime'))
{
class DateTime
{
var $date;
function __construct($date = "now", $tz = null) {
$this->date = strtotime($date);
}
function setTime($hour, $minute, $second = 0) {
$this->date = strtotime(date("Y-m-d", $this->date)."
".$hour.":".$minute.":".$second);
}
function setDate($year, $month, $day) {
$this->date = strtotime($year."-".$month."-".$day."
".date("H:i:s", $this->date));
}
function add(DateInterval $interval) {
self::modify('+'.$interval->sec.' sec');
}
function sub(DateInterval $interval) {
self::modify('-'.$interval->sec.' sec');
}
function setTimeZone($timezone) {
return;
}
function modify($multiplier) {
$this->date = strtotime($this->__getDate() . ' ' . $multiplier);
}
function format($format) {
return date($format, $this->date);

$string = strtoupper($string);
if ($string{0} != 'P')
throw new Exception("'P' expected as first character in
'".$string."'");
