DateTimeZone::listIdentifiers
This class became available in PHP 5.3. It is not present in 5.2 or earlier releases. I found this out the hard way when you PHP scripts stopped working when I deployed them onto a Yahoo server. Yahoo has 5.2 while my machine hosts 5.3.
The DateInterval class
Introduction

It would be nice that when converting a DateInterval to a string, the interval specification used to construct the object is returned (like "P2W").
I need this to serialize a DateInterval object in order to store it in a postgres DB.
