tzdb.txt

The rule definition in the Olson database. A tool called zic parses these rules, instantiates all individual transitions in a given timeframe and then stores these instances in a binary format that ships with most UNIXes and the python zoneinfo module. All clients just parse those binary files with the specific transition dates, which do not contain any 'meta' information about the rules behind the transition dates.

zoneinfo.txt

The data I was able to extract from zoneinfo instances, as long as the plain-python implementation was used instead of the C-module.
