This has been beaten to death in the archives, but once again for the
record, it's going to stay like this.

my $dt1 = DateTime->new( month => $month, year => 2002 );
my $dt2 = $dt1->clone->add( months => 1 )->subtract( seconds => 1 );
There are several variations on the above that'd work.

No, it seems like a way to encourage people to write really weird code
that doesn't really demonstrate their _intent_. The next person after you
to read the code you posted will be sitting there think "second = -1,
WTF?". If they read the code above, they'll think "datetime math, ok".
