Re: [Omaha.pm] DateTime::Duration ->days()

[Sterling Hanenkamp <sterling@hanenkamp.com>]

In DateTime, you want delta_days... twice.

my $start = DateTime->new(year => 2007, month => 5, day => 15);

my $end = DateTime->new(year => 2011, month => 1, day => 14);

say sprintf('$%0.2f', 1025 / $end->delta_days($start)->delta_days);

DateTime is popular because it is accurate, common, standard, extensible, and popular (since popularity is a property that feeds itself), not because it is fast or easy to use by itself (it is neither in my experience).

See? Easy...


$ cat j2.pl
use 5.12.0;
use Date::Calc qw(Delta_Days);

say sprintf('$%0.2f', 1025 / Delta_Days(2007, 5, 15, 2011, 1, 14));

$ perl j2.pl
$0.76


My laptop died today. And that's how much money it cost me per day I owned it. Used it daily. Not bad.  :)
