Methods Documentation

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. This is the base method that ignores parent and requires that subclasses implement the value property. Subclasses that require parent or have other optional args for to_value should compute and return the value directly.
