libdata-formvalidator-constraints-datetime-perl binary package in Ubuntu Xenial armhf

 Data::FormValidator::Constraints::DateTime provides constraint routines for
 Data::FormValidator based upon the DateTime module. It provides an easy
 mechanism for validating dates of any format (using strptime(3)) and
 transforming those dates (as long as you 'untaint' the fields) into valid
 DateTime objects, or into strings that would be properly formatted for
 various database engines.
