  Methods Documentation

  mask_if_needed(value)
  set_jds(val1, val2)

    Set internal jd1 and jd2 from val1 and val2. Must be provided by derived classes.

  to_value(**kwargs)

    Return time representation from internal jd1 and jd2 in specified `out_subfmt`.

    This is the base method that ignores `parent` and uses the `value` property to compute the output. This is done by temporarily setting `self.out_subfmt` and calling `self.value`. This is required for legacy Format subclasses prior to astropy 4.0 New code should instead implement the value functionality in `to_value()` and then make the `value` property be a simple call to `self.to_value()`.

    Parameters:
      parent `object`

        Parent `Time` object associated with this `TimeFormat` object

      out_subfmt `python:str` or `python:None`

        Output subformt (use existing self.out_subfmt if `None`)

    Returns:
      value `numpy.array`, `numpy.ma.array`

        Array or masked array of formatted time representation values
