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
               },
           }
