Help understanding perl script
Hello,

A former sys admin placed this script on one of our boxes and it needs to be adjusted, but I'm not familiar with perl. Can someone help break this down for me? I'm particularly interested in the -mtime function. What's the time frame being referenced here.

Code:
open(HD,"/usr/local/src/files.txt");
system("/bin/rm -f /tmp/text.txt");

$line = <HD>;

while($line) {

  @ar=split(/\s+/,$line);
  chomp($ar[1]);
  print("$ar[0]\n");
  system("/bin/find $ar[0] -mtime $ar[1] -type f -print >> /tmp/text.txt");
  system("/bin/find $ar[0] -mtime $ar[1] -type f -exec rm -f  \{\} \\\; >> /tmp/text.txt");
  $line = <HD>

       sieveshell --help

DESCRIPTION

       sieveshell allows users to manipulate their scripts on a remote server.	It works via MANAGESIEVE, a work in progress.

       The following commands are recognized:

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

OPTIONS

       -u user, --user=user
	   The authorization name to request; by default, derived from the authentication credentials.

       -a authname, --authname=authname
	   The user to use for authentication (defaults to current user).

       -r realm, --realm=realm
	   The realm to attempt authentication in.

       -e script, --exec=script
	   Instead of working interactively, run commands from script, and exit when done.
