time.get_clock_info(name)
-------------------------
Get information on the specified time function as a dictionary. Only the following
names are accepted:
Get information on the specified clock. Supported clocks:
* "clock": time.clock()
* "highres": time.highres()
* "monotonic": time.monotonic()
* "time": time.time()
The following keys are always present:
Return a dictionary with the following keys:
* "function" (str): name of the underlying operating system function (ex:
"QueryPerformanceCounter()" or "clock_gettime(CLOCK_REALTIME)")
* "resolution" (float): resolution in seconds of the function
* "is_monotonic" (bool): True if the clock is monotonic
* Mandatory keys:
* "function" (str): name of the underlying operating system function.
Examples: "QueryPerformanceCounter()", "clock_gettime(CLOCK_REALTIME)".
* "resolution" (float): resolution in seconds of the clock
* "is_monotonic" (bool): True if the clock cannot go backward
* Optional keys:
* "accuracy" (float): accuracy in seconds of the clock
* "is_adjusted" (bool): True if the clock can be adjusted (e.g. by a NTP
daemon)
