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
                       },
               }
