1- Was just lazy and copied the code from the calling cron job.
2- Didn’t know about most of those, and now I do, and will probably switch to one of them really soon.

Thanks, this is helpful!

1. why shell out to the date command (making the script slower and less portable) when we have localtime and POSIX::strftime?
2. why are you escaping %? (it doesn’t interpolate)?
3. why use a non-standard date option to get yesterday?

What is so wrong with

    my $today = DateTime->now->ymd;

or

    use POSIX qw/strftime/;
    my $today = strftime “%Y-%m-%d”, localtime;

and

    my $yesterday = DateTime->now->subtract( days => 1 )->ymd;

or

    $ENV{TZ} = “EST+28”;
    my $yesterday = strftime(“%Y-%m-%d”, localtime), “\n”;
