Victor, I think that steady can always be monotonic, there are time sources enough to ensure this on the platforms I am aware of. Strict in this sense refers to not being adjusted forward, i.e. CLOCK_MONOTONIC vs CLOCK_MONOTONIC_RAW. Non monotonicity of this call should be considered a bug. Strict would be used for profiling where forward leaps would disqualify the timing. -------------- next part -------------- An HTML attachment was scrubbed...
