[Python-Dev] PEP 418 is too divisive and confusing and should be postponed

time.clock_gettime() & friends were added by the issue #10278. The
function was added before someone asked (me) to write a PEP. The need
of a PEP came later, when time.wallclock() and time.monotonic()
functions were added.

time.clock_gettime() can be used for other purpose than a monotonic
clock. For example, CLOCK_THREAD_CPUTIME_ID is the only available
function to get the "Thread-specific CPU-time clock". It also gives
access to CLOCK_MONOTONIC_RAW which is not used by the
time.monotonic() function proposed in the PEP.
