code: def sleep_for_interval(self, start_ts, nseconds):
          
          sleep_time = nseconds - (time.time() - start_ts)
          if sleep_time <= 0:
              return
          self._logger.debug('Sleeping for %s', sleep_time)
          # Recompute time to sleep to improve accuracy in case the process was
          # pre-empted by the kernel while logging.
          sleep_time = nseconds - (time.time() - start_ts)
          if sleep_time > 0:
              time.sleep(sleep_time)
docs: Sleep for a given interval with respect to the start timestamp.
  
          So, if the start timestamp is 1337 and nseconds is 10, the method will
          actually sleep for nseconds - (current_timestamp - start_timestamp). So
          if the current timestamp is 1340, we'll only sleep for 7 seconds (the
          goal being to sleep until 1347, or 1337 + 10).
