I think the problem is that the root filesystem is never really
read-only because the kernel does journal replays and things
like that, too eatly (there was quite some discussion around
this, and tytso never saw the error because he was west of UTC
or something like that).

I think that distributions run hwclock, check filesystems,
then run hwclock again, even. But, see above, it may not
be enough. I seem to recall an answer from that discussion
simply saying to “fix your clock”, so, it may be the kernel
that needs to set the correct time (and timezone).

Does the MacOS store the timezone, anyway?

(In BSD we have it compiled in the kernel… while that can
be changed on a compiled kernel like Linux rdev could, it
isn’t the nicest way either.)

was still ffs, and the sys admins knew it was good. :)  -- Ted Unangst über *fs
