I am happy to change the patch as needed.  However, since the kernel
does not have access to a timezone database and therefore cannot
convert timezone names to offsets, perhaps the mount option should be
something like "tzoffset=0", "tzoffset=1200" etc., with "tzoffset=0"
being equivalent to the "posixtime" option implemented by my patch.
