Methods Documentation

set_jds(val1, val2)[source]¶: Set internal jd1 and jd2 from val1 and val2. Must be provided by derived classes.

to_value(**kwargs)[source]¶: Return time representation from internal jd1 and jd2. Subclasses that require parent or to adjust the jds should override this method.
