Report "00", IMVHO. There's no year "0" so year 1 AD is "CC=1, YY=1". Year
100 is "CC=1, YY=00", year 1000 is "CC=10, YY=00", year 2000 is "CC=20, YY=00"
(1900 is "CC=19, YY=00"). Centuries change on years ending with '01', years
ending with '00' are from the previous century :-)
But for millenia the thing is diffent... ;-) (Just to complicate a bit more)

I can't answer that... But my expectations are like Akio's.
