Thanks for reporting this.  (But surely you needed to add a Rule line
as well?)

I have circulated some proposed patches on the tz mailing list and
expect they'll be installed in due course onto the canonical copies at

patches I proposed.  These patches guess that daylight saving time
will expire on September 11, but of course this could change.

Right!  Sorry for not copying them, but they are very similar to yours.

For the tz database, you can visit .
You can also subscribe to the tz mailing list as described in
 (look for "subscribe").

For Debian, you can visit
