These changes add more bugs than they fix.
I tend to think all this clock business should be done local to those arches that aren't capable of providing cheap, useful synchronised and accurate clocks themselves. Or be a lib that they can link in if needed. As it stands, it seems to me that it all just penalises those architectures that have decent clocks.
