Yes, real time is the reference when I say that CLOCK_MONOTONIC is
steadier than CLOCK_MONOTONIC_RAW.

I agree that CLOCK_MONOTONIC is not steady from the real time
reference when the system is suspended. CLOCK_BOOTTIME includes
suspend time, but it was only introduced recently in Linux.

Because the "steady" name is controversal, I agree to use the
"monotonic" name. I will complete the section explaning why
time.monotonic() is not called steady :-)
