Bug description: decimal values fed to DateTime->modify() causes long execution times
Description:
------------
Feeding a decimal value to DateTime's modify() function can cause very
long execution times because the decimal point is ignored.
Reproduced on the php5.3-200808200230 snapshot.
Reproduce code:
---------------
$date = new DateTime();
$date->modify("+1.61538461538 day");
Expected result:
----------------
A warning or exception, or perhaps 1 day + 0.61538461538*24 hours added.
Actual result:
--------------
after 32 seconds of execution, 161538461538 days are added to the date
