For comparison with the IANA tz data, the IATA has a database of time zones as an appendix to a document called SSIM. That consists of records of 390 ASCII characters in columns at a cost of $1329.00 USD https://www.iata.org/publications/store/Documents/Passenger%20Standards/spec...
SSIM is structured as the offsets currently in effect; history is not included. It is unclear to me why an airline would subscribe to this information rather than rely on IANA tz.
Does IANA have access to this IATA data? Can anything be learnt from a regular comparison of offsets? -- John
