docs: Extract semantic date information from an input string.
      This is a convenience method which would only be used if
      you'd rather not initialize a DateService object.
  
      Args:
          inp (str): The input string to be parsed.
          tz: An optional Pytz timezone. All datetime objects returned will
              be relative to the supplied timezone, or timezone-less if none
              is supplied.
          now: The time to which all returned datetime objects should be
              relative. For example, if the text is "In 5 hours", the
              datetime returned will be now + datetime.timedelta(hours=5).
              Uses datetime.datetime.now() if none is supplied.
  
      Returns:
          A list of datetime objects extracted from input.
