I disagree with in2nix.
find's behavior is largely very consistent, expecially on versions of UNIX that are POSIX-compliant.
find uses the stat() system call. This returns mtime as seconds since Jan 01 1970, called 'epoch seconds'. mtime +13 means the file's modification time is greater than the number of seconds in a day times 13 - at least (84600 * 13) seconds ago.
Not actual calendar days.
This result for find is from the CURRENT TIME. The time right now in epoch seconds. If you want find to behave the way you think about dates you have to give those it kinds of dates/times in the form of an mtime you set on a dummy file
So, -mtime +days ain't gonna cut it.
touch -t YYYYmmddhhmm [somefilename] sets an exact mtime on a file

Hi,
Suppose if I have a file having data like this:
$ cat file.txt

file::touch
Touch(3pm) User Contributed Perl Documentation Touch(3pm)NAME
File::Touch - update access and modification timestamps, creating nonexistent files where necessary.
SYNOPSIS
use File::Touch;
@file_list = ('one.txt','../two.doc');
$count = touch(@file_list);
use File::Touch;
$reference_file = '/etc/passwd';
$touch_obj = File::Touch->new(
reference => $reference_file,
no_create => 1
);
@file_list = ('one.txt','../two.doc');
$count = $touch_obj->touch(@file_list);
DESCRIPTION
Here's a list of arguments that can be used with the object-oriented contruction:
atime_only => [0|1]
If nonzero, change only the access time of files. Default is zero.
mtime_only => [0|1]
If nonzero, change only the modification time of files. Default is zero.
no_create => [0|1]
If nonzero, do not create new files. Default is zero.
reference => $reference_file
If defined, use timestamps from this file instead of current time. Default is undefined.
atime => $time
If defined, use this time (in epoch seconds) instead of current time for access time.
mtime => $time
If defined, use this time (in epoch seconds) instead of current time for modification time.
Examples
Update access and modification times, creating nonexistent files
use File::Touch;
my @files = ('one','two','three');
my $count = touch(@files);
print "$count files updated
";
Set access time forward, leave modification time unchanged
use File::Touch;
my @files = ('one','two','three');
my $day = 24*60*60;
my $time = time() + 30 * $day;
my $ref = File::Touch->new( atime_only => 1, time => $time );
my $count = $ref->touch(@files);
print "$count files updated
";
Set modification time back, update access time, do not create nonexistent files
use File::Touch;
my @files = ('one','two','three');
my $day = 24*60*60;
my $time = time() - 30 * $day;
my $ref = File::Touch->new( mtime => $time, no_create => 1 );
my $count = $ref->touch(@files);
print "$count files updated
";
