Well, then you answered the question sent to the other list,
which I have not seen and did not know about this context ...

But Ed Maste has meanwhile answered the question he asked on
this list (as far as I understand it):

-> "freebsd-update" applies the timezone changes and EN notes
are sent out to notify users of the availability of this update.

And release users should follow-up on EN notes anyway and thus
should not miss the timezone updates.
