Thanks to an application created at NASA's Goddard Institute for Space Studies, we can now know what time it right now on Mars. And you can download the app from weblog Boing Boing, for Mac, Windows, Linux, OS/2, and other open operating systems
Mars24 is a Java application, which displays a Mars sunclock, a graphical representation of the planet Mars showing its current sun- and nightsides, 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 and path for a given location on Mars.
