Time changed back to old daylight savings

Well, since I didn't install it from source, but a snapshot, I don't have
the northamerica source to get an MD5 # on.

Isn't there some other way to update the zone info files to fix this?

This tends to indicate the your /etc/localtime file is wrong. The
timeservers all return UTC; the display for the date consults /etc/localtime
to display UTC time in local time.

This indicates that your zoneinfo files have not been updated correctly.

Which definitely isn't the correct fix.

What does "md5 /usr/src/share/zoneinfo/northamerica" return? (I'm assuming
that you're in North America). On my 6-STABLE machine it's:

 MD5 (/usr/src/share/zoneinfo/northamerica) =

Any other result means that your should re-cvsup, and rebuild your system
again. If it is the same, make sure your zoneinfo files have been rebuilt
(check the file timestamps).
