Title: bug with deprecated timezone in form framework

I found a problem with form framework when using a deprecated timezone.

I used deprecated timezone US/Central, and could not validate the date
fields. Got the error "invalid date", eventho i could not choose different in the select box of dates..

Havent tested all deprecated timezones, but think it gives sence to give
the user an error un deprecated usage of php.
