Free lander software for pda

MarsClock is an alarm clock for Mars time. It was created to aid the NASA MER and Phoenix robots. Many clocks exist for Mars, but none were portable nor had alarm capabilities at the time this was created.
MarsClock is a port of Mars24, created using OnBoardC. It runs on the PalmOS operating system (v 3.0 through 5.2) and requires MathLib. The error between MarsClock and the JPL MER time sheets is less than one minute for the nominal mission duration.
This software is free. You are free to view the source code, modify it, and/or use it elsewhere as per the GPL.
