New Mars Forums

A good Mars timekeeper is a Cookoo, or pendulum clock, as the pendulum weight is adjustable.  Another (less expensive) way, is to get hold of a cheap battery clock unit, (the type you would buy for homemade ceramic or wooden clocks). These all have a "time +/- ajustment". The three I have tried, all easily slow down to the 1.03 Mars differential. (+37 minutes per Earth day). (Mars clock runs 37 minutes slower than Earth time.))                           Example: set the Mars clock to Your local time, say 6 p.m., adjust, so at 6 p.m. the next day the Mars clock has lost 37 minutes. (should read 5.23 p.m.). So if you are watching Mars time, it is not too hard to keep track of am/pm on Mars.                   
Battery Digital clocks will give you am/pm, (And many will have an adjustment), If this is a resistor or capacitor, you can change the value to suit,  Have fun, Ric,,,
