Frank,
You ask:
"Does the app author update this manually? Or is it taken from an automated feed? You should be able to determine that after a few weeks. I suspect, though, that these coordinates match the rover's location on day one. How far has it travelled since then?? How much would this affect local solar time (not that they would keep local time for mission planning ...but maybe worth knowing as a "curiosity")."
The time is taken from an algo automated feed shown in sub menu - Live Calculations. I also found under sub menu - About 1.1 that the Curiosity Position is the landing position. The author is : Mark Burrell - mars(at)digitaltrust.co.uk
Four different time options are offered on the main page: Local Mean Solar Time LMST, Local Mean Zone Time LMZT, Local True Solar Time LTST, and Spacecraft Event Time SCET (used by mission handlers).

P.S. This Mars Time app looks like some pretty good work to me.
