Thanks to Staczilla for this link.
The website describes this application as:
Mars24 is a cross-platform Java application and applet which displays a Mars "sunclock", a graphical representation of Mars showing the current sun- and nightsides of Mars, along with a numerical readout of the time in 24-hour format. Other displays include a plot showing the relative orbital positions of Mars and Earth and a diagram showing the solar angle for a given location on Mars.
You can also track the location of Beagle II, Viking II, the Mars Orbiters, Pathfinder and the new Spirit and Opportunity landers.
I just keep adding to my list of applications running on my machine at any given time :)
