Stopwatch has millisecond accuracy and no artificial limit on hours. Stopwatch runs on UNIX, Windows, and MacOS.
Stopwatch normally runs as a standalone program. To run it this way, download and install it. You can also run stopwatch inside the browser, if you have the Tcl plugin.
Press "start" to start the stopwatch and "stop" to stop it. "record" records the current time and selects it so that it can readily be pasted into other programs. Recorded times are marked with an L for "lap" or T for "total". When stopped, you can cut/paste/edit the time by hand and set it to any valid time. "zero" resets the time to zero. Holding down the shift key while pressing record or zero, records and then zeros the time.
Time moves forward or backward according to the Run menu. By default, time is stopped automatically when either the lap or total time reaches zero. To disable the automatic stop, unselect Run -> Stop At Zero.

There is no installation step (such as "configure" or "Make"). Once downloaded, simply run stopwatch with wish or any Tk-enabled interpreter. If you're unfamiliar with wish or Tk, download the Tcl/Tk distribution from the Tcl Developer Xchange.
Stopwatch requires Tcl/Tk 7.5 or later. Millisecond timing is available when using Tcl 8.3 or later.
By default, the maximum time is just over 596 hours (about 25 days). The range may be increased (to about 68 years) by disabling the millisecond timer. To disable the millisecond timer, unselect Run -> Milliseconds.
