I agree.
I think that this is a better way to do it, because it keeps DateTime
object inheritance and it takes care of 'locale' and other internals:
my $tmp_dt1 = $dt->clone->truncate( to => 'day' );
# $tmp_dt1->set_time_zone( 'UTC' )
# if $tmp_dt1->time_zone->is_floating;
my $rise_time = $tmp_dt1 + $rise_dur;
my $set_time = $tmp_dt1 + $set_dur;
return ( $rise_time, $set_time );
How about this:
This module understands "floating times" as being at time zone
offset 00:00, because there is no such things as floating sunrise or
sunset times.
