=head1 NAME
Data::Sah::Compiler::js::TH::duration - js's type handler for type "date"
=head1 VERSION
This document describes version 0.83 of Data::Sah::Compiler::js::TH::duration (from Perl distribution Data-Sah), released on 2016-06-12.
=head1 DESCRIPTION
Currently the C<duration> Sah type is represented in JavaScript using number
(float, number of seconds). In the future, a choice of coercing to some duration
object might be supported, for richer manipulation, like L<DateTime::Duration>
in Perl.
