I’d be satisfied if software that relies on the tz database simply warned users that DST info prior to 1970 may not be correct.
It's nice to see a fellow data user who has found TZ for much the same reason. I've been banging my head against this brick wall for a number of years now after finding genealogical data that we could not decipher because it did not even reference which version of TZ had been used to create it. At the very least there should be warnings but in addition it would be nice if well researched material was included by default and not relegated to the little used 'backzone' file. Much of my UK material relies on data in there which may or may not be available to the user - with no warning :( -- Lester Caine - G8HFL ----------------------------- Contact - https://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - https://lsces.co.uk EnquirySolve - https://enquirysolve.com/ Model Engineers Digital Workshop - https://medw.co.uk Rainbow Digital Media - https://rainbowdigitalmedia.co.uk
