If you want to create the DateTime object directly from a timestamp use this
<?
$st = 1170288000 // a timestamp
$dt = new DateTime("@$st");
?>

"String in a format accepted by strtotime()" is not 100% truth - you cannot pass timezone info in the string used as DateTime constructor, while you can do it with strtotime(). It may be a problem if you would like to create a date from GMT time and then display it in your local timezone, for example:
<?php
$timeZone = 'Europe/Warsaw'; // +2 hours
date_default_timezone_set($timeZone);
$dateSrc = '2007-04-19 12:50 GMT';
$dateTime = new DateTime($dateSrc);
echo 'date(): '.date('H:i:s', strtotime($dateSrc));
// correct! date(): 14:50:00
echo 'DateTime::format(): '.$dateTime->format('H:i:s');
// INCORRECT! DateTime::format(): 12:50:00
?>
So if you want to convert date between different timezones, you have to create two DateTimeZone objects - one for the input and one for output, like this:
<?php
$timeZone = 'Europe/Warsaw'; // +2 hours
$dateSrc = '2007-04-19 12:50';
$dateTime = new DateTime($dateSrc, new DateTimeZone('GMT'));
$dateTime->setTimeZone(new DateTimeZone($timeZone));
echo 'DateTime::format(): '.$dateTime->format('H:i:s');
// CORRECT! DateTime::format(): 14:50:00
?>
I'm not sure if this is a bug or desired behaviour.

date_create and other DateTime related functions are included by default only in PHP versions equal and greater than 5.2.
In PHP 5.1.2 this functionality is marked to be experimental and has to be enabled at compile time.
