Mission Clock is software for landscape-capable Pocket PCs and compatible devices for the purpose of keeping time on Mars centered around the landing coordinates of the Mars Rovers and Phoenix Lander which touched down safely on May 25, 2008 23:53:36 UTC in an arctic martian region known as Vastitas Borealis.

For all times to show correctly, it is important that the time zone in the device is set to the correct value including compensation for daylight saving, if currently observed. Example, -07:00 hours for Pasadena during PDT or +09:00 hours for Tokyo where DST is not observed. The detected device time zone can be confirmed at the topmost of the Time menu.

Since Version 1.09, this application adds Spirit (MER-A) and Opportunity (MER-B)

1. Select a mission in the Program menu
2. Select the time of interest in the Time menu.
3. Tap on the list of data to view Sun/Earth coordinates
4. Press Analog in the Time menu to switch to analog mode.
5. Press Chart to view Phoenix's location on Mars.
6. Press Weather to view Phoenix's location weather.

Analog mode:
Top left: analog clock for all time modes.
Top right: toggles Earth and Sun centered longitudes every 15 seconds.
Bottom left: toggles Earth and Sun altitude & azimuth every 15 seconds
Bottom right:
    top: Mars's equation of time
    middle: Mars's distance to the Sun
