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:

parentobject

Parent Time object associated with this TimeFormat object

out_subfmtpython:str or python:None

Output subformt (use existing self.out_subfmt if None)

Returns:

valuenumpy.array, numpy.ma.array

Array or masked array of formatted time representation values
