tz-brasil wasn't updating correctly the BRST timezone after upgrade to intrepid from hardy

[Diogo Matsubara]

Binary package hint: tz-brasil

After upgrading from hardy to intrepid my timezone information wasn't updated according to BRST (brazilian summer time)

My workaround to the problem was to remove and re-install the package. (i.e. apt-get remove tz-brasil and apt-get install tz-brasil). That solved the problem as when the package is re-installed it downloads the new tz database.

The actual problem seems to be that tz-brasil has already cached an updated version of the timezone file in /var/lib/tz-brasil/info, but that file was out of date with the rest of the system. Even when I told it to --force, it would download the file but then refuse to update the system zoneinfo database.

I got what the problem is.

It works like this:
 1 - tz-brasil fetches the timezone information
 2 - it compares with the last fetch
 3 - if it finds changes in the fetched file, it runs the command "zic" to "compile" the timezone changes (that saves information in /usr/share/zoneinfo

when we upgraded to intrepid, the tzdata package overwrited the files in /usr/share/zoneinfo

maybe the solution is a better integration with tzdata package...

this would solve:
  1 - change the option of tz-brasil "--force" to run the zic command anyway
  2 - add to tzdata postinst a command to run tz-brasil if it is installed

what do you think about this solution? is there a better one?
