Question

How to get clock info for information about the clock in python

Answer 1

import time
import textwrap     

the_clocks = [         
    ('clock', time.clock),         
    ('monotonic', time.monotonic),
    ('perf_counter', time.perf_counter),         
    ('process_time', time.process_time),         
    ('time', time.time),]
    

for clock_name, function in the_clocks:         
    print(textwrap.dedent('''{name}:             
            adjustable    : {info.adjustable}
