Thats correct. Tests were done incorrectly. The power cable was not removed
the board still had power. 

I have repected fresh all tests. Now, very strange everything is fine. I cant explain
what has happened except:

 * kldunload / load nxprtc 
 
 * creating a new hints file 

 * removing and re-inserting the battery 

I have powered off the board for 2hrs and the time functions correctly. I will soon
setup another RBPI board and re-test all over with the new ko module.
