If have:
my $lookup = $resultset->hashmap_multi( 'k' );
my @info = map { { $_->gethash( 'a d' ) } } @{$lookup->{$k}};
where 'd' is a UnixTime.
this results in datetime() format.
to get a different format, say date(), it seems one must:
my $lookup = $resultset->hashmap_multi( 'k' );
my @info = map { { a => $_->a, d => $_->d->date } } @{$lookup->{$k}};
it would be desirable to be able to simply:
my $lookup = $resultset->hashmap_multi( 'k' );
my @info = map { { $_->gethash( 'a d.date' ) } } @{$lookup->{$k}};
