Question: How do I get a file's timestamp in perl?

    If you want to retrieve the time at which the file was last read,
    written, or had its meta-data (owner, etc) changed, you use the -M,
    -A, or -C filetest operations as documented in the perlfunc
    manpage. These retrieve the age of the file (measured against the
    start-time of your program) in days as a floating point number. To
    retrieve the "raw" time in seconds since the epoch, you would call
    the stat function, then use localtime(), gmtime(), or
    POSIX::strftime() to convert this into human-readable form.

    Here's an example:

        $write_secs = (stat($file))[9];
        printf "file %s updated at %s\n", $file,
            scalar localtime($write_secs);

    If you prefer something more legible, use the File::stat module
    (part of the standard distribution in version 5.004 and later):

        use File::stat;
        use Time::localtime;
        $date_string = ctime(stat($file)->mtime);
        print "file $file updated at $date_string\n";

    Error checking is left as an exercise for the reader.
