Upon request from someone here at UMSF I have created some quick and dirty Mars Clocks for MER-A,B,PHX at http://www.dmuller.net/mars Trying to verify my results, however, I found that virtually every Mars clock provided on the net gives a different time. So which one is correct?

As for the calculation, the way I understand it, all that is required is:
  1. The Earth UTC time of midnight on the landing spot of the spacecraft (i.e. SOL 0, 00:00:00 - or SOL 1 00:00:00 for the MERs)
  2. Calculating from that base using that 1 Mars second has 1027.49125 Earth milliseconds


I have not found any references to (1), so I trial&error until my results match one of the more official looking Mars clocks. But ... which one is the correct / appropriate one?

Using Mars 24 as a base..
For PHX - Dan's page is 5s ahead. The PHX Webpage is 2mins 30s behind.
For MERA - Dans page is 9 mins 6s behind. The MER flash icon is approx 8 minutes behind and MMB is just 2s behind.
