    I know this issue is real far off, but I ran across some info on this
    during the holiday break. I probably won't be retired in 2038, so it will
    directly affect me. :)

    Both my AIX 4.3.3 and 5.2 boxes stop incrementing time after "Tue Jan 19
    03:14:07 2038" using the PERL script below.

    #!/usr/bin/perl
    # I've seen a few versions of this algorithm
    # online, I don't know who to credit.
    # Comments are by William Porquet

    # You may need to change the line above to
    # reflect the location of your Perl binary
    # (e.g. "#!/usr/local/bin/perl").
    # Also change this file's name to '2038.pl'.
    # Don't forget to make this file +x with "chmod".
    # On Linux, you can run this from a command line like this:
    # ./2038.pl
    use POSIX;
    # Use POSIX (Portable Operating System Interface),
    # a set of standard operating system interfaces.
    $ENV{'TZ'} = "GMT";
    # Set the Time Zone to GMT (Greenwich Mean Time) for date calculations.
    # Now count up in seconds of Epoch time just before and after the
    # critical event. Print out the corresponding date in Gregrorian calendar
    # for each result. Does the year jump backward to some other year
    # than 2038?
    for ($clock = 2147483641; $clock < 2147483651; $clock++)
             {
              print $clock; #I ADDED THIS MYSELF BEFORE RUNTIME. WESLEY JOYCE
              print ctime($clock);
             }
