DateTime fractions of a second are ignored when serialized.

A DateTime cannot be correctly serialized and unserialized.

Test script:
$floatTime = '1400580590.47359';

$nowtime = \DateTime::createFromFormat('U.u', $floatTime);

echo $nowtime->format('Y-m-d H:i:s.u T')."\r\n";

echo serialize($nowtime)."\r\n";

Expected result:
2014-05-20 10:09:50.473590 GMT+0000
O:8:"DateTime":3:{s:4:"date";s:19:"2014-05-20 10:09:50.473590";s:13:"timezone_type";i:1;s:8:"timezone";s:6:"+00:00";}


Note: this serialized DateTime includes the fraction, and when it is passed to unserialize(), the fraction is correctly set in the resulting DateTime object.

Therefore unserialize() works, serialize() does not work.


Actual result:
2014-05-20 10:09:50.473590 GMT+0000
O:8:"DateTime":3:{s:4:"date";s:19:"2014-05-20 10:09:50";s:13:"timezone_type";i:1;s:8:"timezone";s:6:"+00:00";}
