code: def data(path, hours, offset=0):
      
      now = time.time()
      end = now - _to_sec(offset)  # Will default to now
      start = end - _to_sec(hours)
      _data = whisper.fetch(path, start, end)
      return all(x is None for x in _data[-1])
docs: Does the metric at ``path`` have any whisper data newer than ``hours``?
  
      If ``offset`` is not None, view the ``hours`` prior to ``offset`` hours
      ago, instead of from right now.
