=head1 NOTICE

This class and its subclasses are private to the
L<Astro::App::Satpass2|Astro::App::Satpass2> package. The author
reserves the right to add, change, or retract functionality without
notice.

=head1 DETAILS

This subclass of
L<Astro::App::Satpass2::FormatTime::DateTime|Astro::App::Satpass2::FormatTime::DateTime>
formats times using C<DateTime->strftime()>. Time zones other than the
default local zone are handled using
L<DateTime::TimeZone|DateTime::TimeZone> objects.

All this class really provides is the interface to
C<< DateTime->strftime() >>. Everything else is inherited.

The L<DateTime|DateTime> C<strftime()> template extensions have been
further extended to add C<'%{calendar_name}'> and some control over
formatting. See the documentation to
L<Astro::App::Satpass2::FormatTime::DateTime|Astro::App::Satpass2::FormatTime::DateTime>
L<__preprocess_strftime_format()|Astro::App::Satpass2::FormatTime::DateTime/__preprocess_strftime_format>
for the details.

=head1 METHODS

This class provides no public methods over and above those provided by
L<Astro::App::Satpass2::FormatTime::DateTime|Astro::App::Satpass2::FormatTime::DateTime>
and
L<Astro::App::Satpass2::FormatTime::Strftime|Astro::App::Satpass2::FormatTime::Strftime>.
