docs: Record a timing.
  
          This method records a timing to the application's namespace
          followed by a calculated path.  Each element of `path` is
          converted to a string and normalized before joining the
          elements by periods.  The normalization process is little
          more than replacing periods with dashes.
  
          :param float duration: timing to record in seconds
          :param path: elements of the metric path to record
