Description:
 def make_a_pause(self, timeout=0.0001, check_time_change=True):
 """ Wait up to timeout and check for system time change. This function checks if the system time changed since the last call. If so, the difference is returned to the caller. The duration of this call is removed from the timeout. If this duration is greater than the required timeout, no sleep is executed and the extra time is returned to the caller If the required timeout was overlapped, then the first return value will be greater than the required timeout. If the required timeout is null, then the timeout value is set as a very short time to keep a nice behavior to the system CPU ;) :param timeout: timeout to wait for activity :type timeout: float :param check_time_change: True (default) to check if the system time changed :type check_time_change: bool :return:Returns a 2-tuple: * first value is the time spent for the time change check * second value is the time change difference :rtype: tuple """
