Name

       App::Sqitch::DateTime - Sqitch DateTime object

Synopsis

         my $dt = App::Sqitch::DateTime->new(%params);
         say $dt->as_string( format => 'iso' );

Description

       This subclass of DateTime provides additional interfaces to support named formats. These can be used for
       status or log "--date-format" options. App::Sqitch::DateTime provides a list of supported formats,
       validates that a format string, and uses the formats to convert itself into the appropriate string.

Interface

   Class Methods
       "as_string_formats"

         my @formats = App::Sqitch::DateTime->as_string_formats;

       Returns a list of formats supported by the "format" parameter to "as_string". The list currently
       includes:

       "iso"
       "iso8601"
           ISO-8601 format.

       "rfc"
       "rfc2822"
           RFC-2822 format.

       "full"
       "long"
       "medium"
       "short"
           Localized format of the specified length.

       "raw"
           Show timestamps in raw format, which is strict ISO-8601 in the UTC time zone.

       "strftime:$string"
           Show timestamps using an arbitrary "strftime" pattern. See "strftime Paterns" in DateTime for
           comprehensive documentation of supported patterns.

       "cldr:$string"
           Show timestamps using an arbitrary "cldr" pattern. See "CLDR Paterns" in DateTime for comprehensive
           documentation of supported patterns.

       "validate_as_string_format"

         App::Sqitch::DateTime->validate_as_string_format($format);

       Validates that a format is supported by "as_string". Throws an exception if it's not, and returns if it
       is.

   Instance Methods
       "as_string"

         $dt->as_string;
         $dt->as_string( format => $format );

       Returns a string representation using the provided format. The format must be one of those listed by
       "as_string_formats" or an exception will be thrown. If no format is passed, the string will be formatted
       with the "raw" format.
