[time-nuts] Android App for UTC vs GPS vs TAI vs Device Time

Hi Folks,

We all know the issue of Android Devices that report GPS as UTC Time,
and  all that goes with it. I do have TAI Clock installed, along with
"UTC Clock" and "Navy Clock"

Now.. Even though I have a Samsung S-2, what I'm really after is an
app that shows the following:

   1) Local Device Time
   2) UTC Time (maybe grabbed from a remote NTP Server)
   3) GPS Time (derived from the GPS constellation, but not making 
system time negative 15 seconds
   4) TAI Time (derived from 1,2, or 3 above..)

I have apps for some combination of the above, but not all. Anyone know
of such an animal ? At least one of the apps seems to say my device is
syunc with GPS, when others suggest it is syncronised with UTC!

[This is also to explain and demonstrate the differences to a friend,
but it would be good to be able to tell what time-frame the S-2 is
working to...]

Best Regards
