All, While it is tough to do, I must cast a -1 for the following reasons:
Given that system VMs write files, this defect makes every file created/modified timestamp unreliable. Operational log correlation/debugging is nearly impossible since the clock is out of sync. It renders S3-backed Secondary Storage unreliable/useless As Ahmad pointed out, there are likely other instabilities/defects lurking due to this issue that we haven't discovered. I think we also need to determine whether or not this issue was introduced in 4.1. If not, we should consider back porting these fixes.
