Your logic escapes me, and it might be quite locale dependent. Here's a somewhat easier approach:
Code:
touch -d"-15days" TMP
[ file -nt TMP ] && echo newer || echo older

shtool-mkln

SHTOOL-MKLN.TMP(1)					      GNU Portable Shell Tool						SHTOOL-MKLN.TMP(1)

NAME

       shtool-mkln - GNU shtool enhanced ln(1) replacement

SYNOPSIS

       shtool mkln [-t|--trace] [-f|--force] [-s|--symbolic] src-path [src-path ...]  dst-path

DESCRIPTION

       This is a ln(1) style command. It is enhanced to provide automatic calculation and usage of relative links with the shortest possible path,
       if possible. Usually if src-path and dst-path are not absolute paths or at least they share a common prefix except the root directory
       (``"/"''). When more than one src-path is specified, all of them are linked into dst-path.

OPTIONS

       The following command line options are available.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

       -f, --force
	   Force the creation of the link even if it exists. Default is to fail with error.

       -s, --symbolic
	   Create a symbolic link instead of a hard-link.

EXAMPLE

	#   shell script
	shtool mkln -s foo/bar baz/quux

HISTORY

       The GNU shtool fixperm command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for ePerl.

SEE ALSO

       shtool(1), ln(1).
