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

Methods Documentation

classmethod fill_value(subfmt)#

Return a value corresponding to J2000 (2000-01-01 12:00:00) in this format.

This is used as a fill value for masked arrays to ensure that any ERFA operations on the masked array will not fail due to the masked value.

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

to_value(jd1=None, jd2=None, parent=None, out_subfmt=None)[source]#: Return time representation from internal jd1 and jd2. Subclasses that require parent or to adjust the jds should override this method.
