[SOFA] Returns the Chronological Julian Day Numbers (if
long) or Julian Day Numbers corresponding
to the specified Gregorian calendar dates
date must have 3 elements in its first dimension (for
year, month, day). The result has the same type as

long, and has the same dimensions as
date except that the first dimension is missing.
Unexpected results may be given if illegal year, month, or day numbers
are specified. Dates before -4799-01-01 yield zero. Dates after
1465073-02-28 yield nonzero but erroneous results (at least on systems
with 32-bit ints).
