Use Argument Clinic for time.clock_gettime() and
time.clock_gettime_ns() functions.
Benchmark on time.clock_gettime_ns():
import time
import pyperf
runner = pyperf.Runner()
runner.timeit(
'clock_gettime_ns(CLOCK_MONOTONIC_COARSE)',
setup='import time; clock_gettime_ns=time.clock_gettime_ns; CLOCK_MONOTONIC_COARSE=6',
stmt='clock_gettime_ns(CLOCK_MONOTONIC_COARSE)')
Result on Linux with CPU isolation:
Mean +- std dev: [ref] 134 ns +- 1 ns -> [change] 55.7 ns +- 1.4 ns: 2.41x faster
