With my latest patch, I can now do this,
% print -P '%D{%y %Ey %f}'
15 27 9
% date +'%y %Ey %f'
15 27 %f

If anyone wants me to make %3f work, I humbly ask them to keep this to
themselves.

Bonus, weird stuff strftime() does:
% date +%014EA #zeropadding the unchanged format string
00000000%014EA
% date +%020Ey #padding Ey is fine
00000000000000000027
% date +%020Oy #but not Oy
=E5=8D=81=E4=BA=94
% date +%_20Oe #not any O* it seems
=E4=B9=9D
% date +%020Oe #applies to english locale too
 9

If you find any problems, please check that it doesn't happen with
date with the same format string.
