PHP 5.1.x has only experimental support for DateTime

http://php.net/manual/en/datetime.installation.php

Note: Experimental DateTime support in PHP 5.1.x

Although the DateTime class (and related functions) are enabled by default since PHP 5.2.0, it is possible to add experimental support into PHP 5.1.x by using the following flag before configure/compile: CFLAGS=-DEXPERIMENTAL_DATE_SUPPORT=1
