Comment(by huhabla):
This must be implemented in the C datetime library and in the temporal
framework parser in datetime_math.py[1]. I hoped that the dateutils[2]
already support this to have it out of the box, but unfortunately they
don't.
Hence we should orient on the ISO 8601 standard for ordinal dates when
implementing this (YYYY-DDD) but not YYYYDDD, since the temporal framework
and the C datetime library also support relative time and can't decide if
1900031 is 31. Jan. 1900 or if it is the number of seconds, days, ... .
