Does IANA have access to this IATA data? Can anything be learnt from a regular comparison of offsets?
I lack access to that data. The late Gwillim Law did have access, which I think was published semiannually on paper, and in the 1990s sent us helpful summaries of discrepancies between the IATA data and ours. As I recall the IATA tables did not record time zone histories, though they did have some provision for planned future changes.
