Hello Holger,

  I don't know how to handle this. Do you have any suggestion? This is
what occours:

  Brazil is "very unstable" regarging daylight-saving-time (DST) start
date and end date. Up to 2009 [1], the dates of changing clock were
reported by government sometimes around 10 days before when it begins.

  In Debian stable, "tzdata" package handle timezone informations, and
since a change in brazilian date of starting the DST is not a security
issue, that can not be generated another package for debian stable, and
brazilian users will have a misconfigured clock.

  So I did tz-brasil package, that tries to fetch periodically the
timezone information from a server [2], and then runs the command "zic"
the "timezone compiler". The compiler then modifies the files that you saw.

  Which whould be a good alternative for handling timezones in countries
that are not well-organized and we have no information, except a few
days before the change will occour?

  Also, in Brazil, we have some states that change DST, and others that
do not have DST. Some years, a state decided to change to DST after
others... That is why I take care of all the brazilian zones in my
tzfile [2] and did this package.

  If this could be considered a good reason for upgrading a new "tzdata"
package to stable, we can remove tz-brasil package from debian. So
Brazilian admins would only have to remember to "apt-get update/upgrade"
periodically.

  I have a non-uploaded version of tz-brasil, which I also check which
processes has a start-timestamp older than the timestamp of file
/etc/localtime. If they are older, then cron sends a warn to root, to
restart that process, or it won't know about the new timezone rules.

  Do you have any opinion?

[1] in 2010 the government changed the rules for DST. Now it is supposed
to be known in advance, but the rule has a relation with carnival date,
and carnival data may change...
