Comment 2 for bug 294435

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?
