I think what you want is absolute days between two dates (the way any human would calculate). You can use following code. This will exactly give you 3 days. I have converted localtime to 12:00 am of the day and i am taking difference. It works :-)
use strict; use Time::Local; my $_timestamp1 = '1189669351'; my $_timestamp2 = '1189395751'; my ($sec1,$min1,$hour1,$mday1,$mon1,$year1,$wday1,$yday1,$isdst1) = lo +caltime($_timestamp1); my ($sec2,$min2,$hour2,$mday2,$mon2,$year2,$wday2,$yday2,$isdst2) = lo +caltime($_timestamp2); my $no_of_days = ((timelocal(0,0,0,$mday1,$mon1,$year1,$wday1,$yday1,$ +isdst1) - timelocal(0,0,0,$mday2,$mon2,$year2,$wday2,$yday2,$isdst2)) +/86400); print "$no_of_days\n";
