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/specifications-utc-app-f.pdf
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.
