NAME
       Data::FormValidator::Constraints::Dates - Validate Dates and Times

SYNOPSIS
	   use Data::FormValidator::Constraints::Dates qw(date_and_time);

	   # In a DFV profile...
	   constraint_methods => {
	       # 'pp' denotes AM|PM for 12 hour representation
	       my_time_field => date_and_time('MM/DD/YYYY hh:mm:ss pp'),
	   }

DESCRIPTION
   date_and_time
       Note: This is a new module is a new addition to Data::FormValidator and is should be considered "Beta".

       This constraint creates a regular expression based on the format string passed in to validate your date against. It understands the
       following symbols:

	   Y   year  (numeric)
	   M   month (numeric)
	   D   day   (numeric)
	   h   hour
	   m   minute
	   s   second
	   p   AM|PM

       Other parts of the string become part of the regular expression, so you can do perlish things like this to create more complex expressions:

	   'MM?/DD?/YYYY|YYYY-MM?-DD?'

       Internally Date::Calc is used to test the functions.

BACKWARDS COMPATIBILITY
       This older, more awkward interface is supported:

	   # In a Data::FormValidator Profile:
	   validator_packages => [qw(Data::FormValidator::Constraints::Dates)],
	   constraints => {
	       date_and_time_field	 => {
		   constraint_method => 'date_and_time',
		   params=>['MM/DD/YYYY hh:mm:ss pp'], # 'pp' denotes AM|PM for 12 hour representation
	       },
	   }
