# ABSTRACT: perl's type handler for type "date"

=encoding UTF-8

=head1 NAME

Data::Sah::Compiler::perl::TH::date - perl's type handler for type "date"

=head1 VERSION

This document describes version 0.912 of Data::Sah::Compiler::perl::TH::date (from Perl distribution Data-Sah), released on 2022-08-20.

=head1 DESCRIPTION

The C<date> type can be represented using one of three choices: int (epoch),
L<DateTime> object, or L<Time::Moment> object. This choice can be specified in
the schema using clause attribute C<x.perl.coerce_to>, e.g.:

 ["date", "x.perl.coerce_to"=>"float(epoch)"]
 ["date", "x.perl.coerce_to"=>"DateTime"]
 ["date", "x.perl.coerce_to"=>"Time::Moment"]

=for Pod::Coverage ^(clause_.+|superclause_.+|handle_.+|before_.+|after_.+)$

=head1 COMPILATION DATA KEYS

=over

=item * B<coerce_to> => str

By default will be set to C<float(epoch)>. Other valid values include:
C<DateTime>, C<Time::Moment>.

=head1 CONTRIBUTING


To contribute, you can send patches by email/via RT, or send pull requests on
GitHub.

Most of the time, you don't need to build the distribution yourself. You can
simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your
system), you can install L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<Pod::Weaver::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond
that are considered a bug and can be reported to me.

=head1 BUGS

Please report any bugs or feature requests on the bugtracker website L<https://rt.cpan.org/Public/Dist/Display.html?Name=Data-Sah>

When submitting a bug or request, please include a test-file or a
patch to an existing test-file that illustrates the bug or desired
feature.
