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. Subclasses that require
parent
or to adjust the jds should override this method.
