Methods Documentation

mask_if_needed(self, value)
set_jds(self, val1, val2)

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

to_value(self, **kwargs)

Return time representation from internal jd1 and jd2. Subclasses that require parent or to adjust the jds should override this method.
