Hi,
I think we need to restart the time API discussion and specify it only wall
time in mind. CPU cycle count APIs can be tuned as a next step. CPU cycle
counters are affected by frequency scaling, which makes those difficult to use
for counting linear, real time. The time API should specify a
Hi, Petri
We have to look at it proceeding from performance, platform portability and
simplicity
If you want to split on hi-res time and low-res they must have separate
functions and
be not under one common opaque time in order to not break hi-res measurements.
But in fact you split the same
One correction, that also makes me worry a little.

It doesn't sound like simplification. In current variant user don't
