Earth Timekeeping to Mars Timekeeping Conversions

Because I’m going out to see family today - might as well get something done. I was going to add “mktime” but I realized that I’ve done Mars to Earth but not vice versa. Besides, I need an “epoch” to start time from.

Technically, I already had done this with mars_time(), I just needed to do it with any timestamp. I did “0” (January 1, 1970, midnight) locally to verify, then chose the Mariner 9 enter orbit as a testcase.

I will note, Wikipedia shows MSD (Mars Sol Date) but also Mars Julian Sol. I wonder if I’ll have to do that later.

I also will probably need to organize my tests/Makefile.am for further testcases. It will grow once I start adding time tests and not just MSD.
