/*
1879-03-14 00:00:00
In the Netherlands Albert Einstein would now be 134 Years, 5 Months, 14 Days, 17 Hours, 54 Minutes, 49 Seconds old.

1879-03-14 00:00:00
In the United Kingdom Albert Einstein would now be 134 Years, 5 Months, 14 Days, 16 Hours, 55 Minutes, 17 Seconds old.

1950-03-14 00:00:00
the Netherlands mr. Anonymous would now be 63 Years, 5 Months, 14 Days, 17 Hours, 55 Minutes, 17 Seconds old.

1950-03-14 00:00:00
In the mr. Anonymous would now be 63 Years, 5 Months, 14 Days, 16 Hours, 55 Minutes, 17 Seconds old.

 now note the difference in seconds between example 1 and 2 of 28 seconds... exactly the time that does not exists in the netherlands on 1937-07-01

 I conclude PHP does it correctly and Zend\Validate\DateStep should account for this.
