OK, fine, than the touch man page should say

BUGS
	The optional timestring doesn't work if you don't own the file,
	even though you can write to it.  In that case consider
	copying the file, touching it to the preferred date, moving it
	to the original file name, if possible, then chown(1) and
	chgrp(1)ing the file to the original owner.

[I haven't considered any of the options letters.]
