in reply to Re^2: Getting previous dates from the current date
in thread Getting previous dates from the current date

Rather than time(), I'd suggest using...

use Time::Local; my $time = timelocal(0, 0, 12, (localtime)[3, 4, 5]);

This'll make midday your starting point for calculations, which helps sidestep the whole daylight savings issue Smylers pointed out.

As an added bonus, Time::Local is also part of the core distribution, so you don't need to install anything via CPAN (which is good, as some of those other more fancy Date:: modules are mighty bloaty!).
