Yesterday was clock-forward time for most of the US and Canada, but my N810 failed to switch. I only bought it a few weeks ago, AND I upgraded to the latest OS2008 53.1 or whatever. Canada decided to follow the US on this province-by-province, but BC decided on 31 March 2006 and the Linux zone sources were updated the next day. So I'm wondering why Nokia has failed to update given nearly 2 years notice. In Maemo, timezones are in the libc6 package. I have maemo-scratchbox-4.0.1 and the zones weren't all correct there, either. But I was able to update libc and that seemed to fix Vancouver. Prior to that, I was able to recompile the North American rules with zic and copy the Vancouver zone to my N810, solving my immediate problem, as per my page http://andrew.triumf.ca/dst.html I have made a stab at collecting updated Canadian zones from my FC4 system (just because I've got it. It should really be done from source) and made http://andrew.triumf.ca/N810/repository/dists/chinook/free/binary-armel/tzdata-canada-2006.deb this wants to overwrite files from libc6 but is not a complete replacement for libc6. Not sure how to do it in apt-get, but this works: dpkg -i --force-overwrite /var/cache/apt/archives/tzdata-canada-2006_2006g_armel.deb so now $ zdump -v America/Yellowknife|grep 2008 gets America/Yellowknife Sun Mar 9 08:59:59 2008 UTC = Sun Mar 9 01:59:59 2008 MST isdst=0 gmtoff=-25200A instead of America/Yellowknife Sun Apr 6 08:59:59 2008 UTC = Sun Apr 6 01:59:59 2008 MST isdst=0 gmtoff=-25200 -- Andrew Daviel, TRIUMF, Canada Tel. +1 (604) 222-7376 (Pacific Time) Network Security Manager
