WMitime is a clock dock app, with excessive praise amongst similar applications available.
One of WMitime's notable features is that it displays both standard time and date, as well as Swatch's internet time (if that matters to you).
To use WMitime, you'll need WindowMaker. Once you have that, you can simply do a "cd wmitime" followed by "make" and "make install" to install it.
If you want to explore WMitime's capabilities further, you can always input "wmitime -h" to display its various available options.
