Python | time.get_clock_info() method

Time module in Python provides various time related functions.

time.get_clock_info() method in Time module is used to get the information on the specified clock name. This method return the information as a namespace object.
The name of supported clocks and the method used to read that clock value are as follow:

  • clock : time.clock()
  • monotonic : time.monotonic()
  • perf_counter : time.perf_counter()
  • process_time : time.process_time()
  • thread_time : time.thread_time()
  • time : time.time()

Syntax: time.get_clock_info(name)



Parameter:
name: A string value representing the clock name.

Return type: This method returns a namespace object whose attributes represents the information about specified clock name.
Following are the attributes of namespace object:

  • adjustable: This is ‘True’ if the clock can be changed automatically or manually by the system administrator. Otherwise ‘False’.
  • implementation: The name of the underlying C function used to get the clock value.
  • monotonic: It’s value is true, if the clock can not go backward. Otherwise False.
  • resolution: This attribute specify the resolution of clock in seconds.

Output:

Information on 'clock':
namespace(adjustable=False, implementation='clock()',
monotonic=True, resolution=1e-06)

Information on 'perf_counter':
namespace(adjustable=False, implementation='clock_gettime(CLOCK_MONOTONIC)',
monotonic=True, resolution=1e-09)

Information on 'process_time':
namespace(adjustable=False, implementation='clock_gettime(CLOCK_PROCESS_CPUTIME_ID)',
monotonic=True, resolution=1e-09)
