The problem I have (and perhaps the DateTime bug) is the ->truncate( to => 'month' ), correct? I need to find the current month in *the target time zone*, so does this usage make sense? Or is there an easier way? my $now_in_amman = DateTime->now( time_zone => 'Asia/Amman' ); my $dt_first_day = DateTime->new( year => $now_in_amman->year, month => $now_in_amman->month, day => 1, hour => 12, # Assume this exists minute => 0, second => 0, ); my $dt = day_start( $dt_first_day->clone, 'Asia/Amman' ); Apr 1, 2016 1:00:00 AM +0300 And for the end time of the month (to the second): $end_dt = day_start( $dt_first_day->clone->add( months => 1 ), 'Asia/Amman' )->subtract( seconds => 1 ); Apr 30, 2016 11:59:59 PM +0300 I was thinking of an implementation that assumed DST change happened at an hour boundary and simply try incrementing hours until no more exceptions. But, I suspect there's places where DST might change at a 1/2 our mark, too -- or at any random time during the day. -- Bill Moseley mose...@hank.org
