<?php $originalDate = new DateTimeImmutable('2011-11-11'); $modifiedDate = $originalDate->modify('+1 year'); assert($originalDate !== $modifiedDate); assert($modifiedDate->format('Y-m-d') === '2012-11-11'); assert($originalDate->format('Y-m-d') === '2011-11-11');

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
