It certainly sounds like all problems could be attributed to the clock
not working correctly. I can't say for certain though, as I don't have
the same hardware, nor any other hardware that shows the same symptoms.
You can probably answer better which of the other possible options are
better than I can, since you've got the hardware. Try them both, see if
either or both give you better results.
