Since Apple updates the timezone information on each dot release of the operating system, you may find that your country is changing to another timezone before Apple releases its update. Such is the case of Argentina, where the dates are confirmed only a few weeks before DST starts.
To overcome this, we created a pkg installer to update zoneinfo and ICU to the latest version available (2008g) that includes the updated timezone information we need in Argentina.
When creating it, we saw that several cities outside Argentina were affected (mainly in Brasil) so we are making this package available to anyone who wants to try it (even if some screens during the installer are only in Spanish).
The package can be downloaded here:
A few comments/warnings:
- This update modifies system files (albeit leaving a backup), so make sure you know what you are doing before running it.
- The update modifies the two databases Mac OS X uses for timezones (zoneinfo and ICU). Some iCal events may be affected if you created them before changing the timezone.
- The update package leaves a copy of your original files, so it can be reverted with a few Terminal commands:
sudo rm -fr /usr/share/zoneinfo sudo rm -fr /usr/share/icu sudo mv /usr/share/zoneinfo.orig /usr/share/zoneinfo sudo mv /usr/share/icu.orig /usr/share/icu
We hope you find this update as useful as we do.
