Ok. The host OS time is fine so I'd have no problem using that
as the source for my linux guest.
What no one has provided yet is an answer to 'how' to get the
linux guest VM to get the proper time from the host?

I'm going to end this particular line of discussion because
it is clear that this is a fruitless conversation and arguing
back and forth about my personal ability to code a solution for
VM time syncronization doesn't do anything for the problem at
hand.
