I suspect it's not needed at all.
Actually I looked into this, and it is needed. We added it to fix a
bug, which was to do with files being created with the wrong dates &
times.
On the other hand it may not be necessary now. I tried commenting it
out and doing various tests, and the dates of files seem correct (even
with TCG with is not using kvm-clock).
It doesn't seem to do any harm to keep it. 'time' indicates that it
takes 0.14 seconds to run (on my laptop, with KVM).
