Hi Mike, I tried that this way:

my $time_string = strftime "%Y-%m-%d", gmtime($mtime);
    if ($time_string =~ 2013-04-01 && ($1>=01 && $1<=20)) {
        print "File $name has an mtime of $time_string\n";
        $ftp->get($name)
                or die "get failed ", $ftp->message;

And it still didn't work for me. You see, what I'd like for it to do is change the day only incrementally from the 1st of the month to the 20th of the month (as in the example above) Is there any way I could do that using your code?
