(the above times are apparently in Tracy's local (TZ) time)

I used HourGlass to set the date/time to Tue Jan 19 03:14:04 GMT 2038,
which is 3 seconds before the overflow, and then watched what would
happen with the HP-UX "date" command:

(oz#sieler) source/hourglass: date
Tue Jan 19 03:14:04 GMT 2038

(oz#sieler) source/hourglass: date
Tue Jan 19 03:14:07 GMT 2038

(oz#sieler) source/hourglass: date
Fri Dec 13 20:45:52 GMT 1901

(oz#sieler) source/hourglass: date
Fri Dec 13 20:45:53 GMT 1901
