Hi Mario,

If you were able to compile the tzdata2009p on the mac os x, then you should be able to download an earlier version of tzdata and compile that to restore the mac. If you want to use the "original" files and don't have a mac than hasn't been updated, you can also download earlier updates or the original install software (depending on how far back you have to go) and then use a utility like Pacifist to extract the Argentina tz fille.

The mac does behave very wacky if the ICU database and the tzdata don't agree, different parts of the system reading from one or the other, and some from a combination of the two! If you would like to learn how to compile the mac ICU database I can point you to some links and share some of my experience (off list, unless others would consider it a suitable list topic). I do this myself to support Macs that are running XJ time, still not incorporated into official databases.

Please let me know where I might be able to help with more detailed directions,
-Luther

I simply compiled the southamerica file from tzdata2009p and that was
it... right? wrong! This actually made the mac go somehow crazy since it
also uses some ICU files which I don't know how to handle.

My friend ended up using Chile's time during the summer and Uruguay's
time after Uruguay's DST period ended. Since a week ago the non-existent
DST for Argentina would have ended, I told him to try again Argentina's
time but it keeps being inconsistent.

Another mac he has at home has now the correct time.

Does anyone know how to restore the original OS X tzdata files without
reinstalling the OS? I know nothing about its packaging system... Mac
users seem to rely on "Apple update" service but I probably f##k'd it up
when I overwrote some files under /usr/share/zoneinfo.

Any help (or links to better places) will be greatly appreciated.
