Doesn't look like anyone ever responded. There is no way to do this currently. You can always just jam the method into the DateTime namespace. That's pretty ugly though.
I guess we could make all the DT::Format modules take a class parameter.
But isn't My::DateTime just another DateTime::Calendar::* really?
It'd be really ugly to do stuff like: $dt = $strptime->parse_datetime( $string, asa => 'My::DateTime' );
So you should do it yourself:
$dt = My::DateTime->from_object(
$strptime->parse_datetime( $string )
);The :Format modules should honor My::DateTime when given them though. (he says, hoping his do)
$http->format_datetime(
My:DateTime->now()
);
The thing that I think that needs to be addressed more is the ability to subclass DateTime and DateTime::Duration. Both have ->isa() in them rather than ->can().
sub _add_overload
....
if ( UNIVERSAL::isa( $d2, 'DateTime' ) ) {
$d2->add_duration($d1);
return;
}
Should be *something* like: sub _add_overload .... if ( $d2->can('add_duration') ) { $d2->add_duration($d1); return; }
(That's not a patch. I haven't tried it. It's just the concept)
If changes like that were made, then you could subclass DateTime and still have it interact correctly with DT:D
