Aktuelles Datum -3 Tage

[Rolf Rost]

weis nicht genau wie das in perl aussieht aber das wäre es in php:

date('Y-m-d',time()-3600*24*3)

in PERL ganz ähnlich:

use POSIX qw(strftime);
my $vorvorgestern = strftime("%Y-%m-%d", (localtime(time - 86400 * 3)) );
print "$vorvorgestern\n"; # 2005-05-03

Gruss, Rolf
