If he wants the date where his computer is located (as opposed to the date somewhere in Europe),
my $thirty_days_ago = DateTime->today(time_zone => 'local')->subtract( +days => 30);

Note that the above solution will fail two days a year in time zones with no midnight on a DST change. (There is at least one such time zone.) Workaround:

my $thirty_days_ago = DateTime->now(time_zone => 'local')->set_hour(12 +)->subtract(days => 30);

[marinersk]: I get a lighter version of this disconcertion (new word?) when the n points remaining until rank disappears.
[choroba]: :-D
[marinersk]: I've often marvelled over the past few decades at just how little it takes to mess me up with this spacial dependence thing. I wonder if I'm mildly autistic or something.
