If only people started to read the docs before complaining that a function doesn't work as they want. Besides that, it's completely useless to call an external program for some functionality that Perl can provide by itself.
First of all, system() does not return the output of a command, but just runs it. What is returned is the exit status of the command, which is the 0 you're seeing. Second, simple date calculation in Perl:

DESCRIPTION
This module provides routines to format dates. They correspond to the libc routines. &strftime() supports a pretty good set of coversions
-- more than most C libraries.
strftime supports a pretty good set of conversions.
The POSIX module has very similar functionality. You should consider using it instead if you do not have allergic reactions to system
libraries.
