This is a time origin of a time coordinate, given as a
Julian Date for the the time scale and reference point
defined. It is usually given as a floating point
literal; for convenience, the magic strings “MJD-origin”
(standing for 2400000.5) and “JD-origin” (standing for 0)
are also allowed.
The time origin is the offset or the time coordinate to Julian
Date. The timeorigin attribute MUST be given unless the time's
representation contains a year of a calendar era, in which case it
MUST NOT be present.
This is the time scale used. Values SHOULD be
taken from the IVOA timescale vocabulary (http://www.ivoa.net/rdf/timescale).
The reference position SHOULD be taken from the IVOA
refposition vocabulary (http://www.ivoa.net/rdf/refposition).
