Hmm, I don't think you're hearing what I'm saying in its intended 
context. But let me table this for now. Can we back up to the other part 
of the thread? If you can point out what I'm missing with the VM clock 
reliability, that would help me better appreciate where you're coming from.

For example, if we were talking about tests between multiple VMs, I 
could immediately appreciate the value of being generous with timing 
margins. But as I indicated in my other message, I'm having difficulty 
seeing how those kinds of problems could arise here.

I apologize if there's something obvious I'm missing or if I'm coming 
across as belaboring an undesirable point. I'm just trying to make sure 
we don't inadvertently rule out a simple solution to the problem that 
could work for everyone.

Thanks,
