The function that has been stolen via third hand from
Communications of the ACM, Vol 6, No 8. is documented as working
for the period in between, and including, 01-01-01 and
65535-12-31, except that non-existing dates are unknown and leap
year calculations do not work correctly until the final
introduction of the gregorian date, 1582-10-15.
I hope that is still correct after so many copies.
