The Chronos date and time library for Smalltalk requires a set of time zone rules to deal with daylight savings time transiations.
The repo includes a probably up to date set of chronos time-zone rules that are updated regularly
- Using a linux that can run a 32bit Pharo 1.3 image
- download this zip file from my dropbox that contains an image+vm+script https://dl.dropboxusercontent.com/u/4460862/chronosUpdater.zip
- unzip the archive and run updateTimeZonesLinux.sh
If things go according to plan the script will download the latest rules, extract them, have Chronos process them, and leave an upated time-zones directory next to the image.
