I also think its a shame that the proposed redefinition of 'tz region' will cause the loss of so much historical data, which is being used by many. I am also concerned with merging Atikokan region (north of Lake Superior) into the Panama region, 5000 km, and a half dozen countries away. I still don't see the proposed redefinition as valuable. If this change is implemented, then a separate database of pre-1970 tz data will be required my many users, as had been suggested (and started) by Tobias Conradi (currently banned) and others. I guess there could be two tz databases. Paul, are you saying that other historical data has been removed from tz in the past, as we might like to capture that old data as well into any new pre-1970 database.

Also, times before 1970 do matter. Whether you are certain or uncertain of the data is less important than not changing the data. In essence the TZDB has become the definition of what time was, irrespective of whether it is accurate or not. As such, history should only be changed if it is demonstratable that the original data was wrong. Seconded! One of my main problems has been getting a reliable base for historic material. Many systems simply ignore dates prior to 1970, but a large number of us are using genealogical databases and need to know that we are working with the same numbers. I also value the pre-1970 data; although I can't claim an impressive user-base for my particular programs, there may well be a fair few projects out there that are quietly making good use of that data.
