<p>In the spirit of TIMTOWTDI, here's an example using [mod://Time::Piece]. The advantage of using Time::Piece is that as of Perl 5.10, it's bundled with Perl core. (As is its companion module [mod://Time::Seconds].)</p>
<code>
use 5.010;
use Time::Piece;
use Time::Seconds qw( ONE_DAY ONE_HOUR );
sub last_day_of_last_month ()
{
my $now = localtime;
my $day = Time::Piece->new(
$now - ($now->day_of_month * ONE_DAY)
);
$day += ONE_HOUR * ($now->isdst <=> $day->isdst);
return $day;
}
say last_day_of_last_month->mdy('/');
</code>
<p>The daylight savings calculation is a bit of an annoyance. :-(</p>
<p>Yeah, that's right; I just did maths with the spaceship operator! :-)</p>
