As an example, consider Sierra Leone https://github.com/eggert/tz/commit/4b4e789d5c5ee79366b4606d139cbb9eb1d5a28d... https://github.com/jodastephen/tzdiff/commit/c812da9e12bd6f8aa52fa2dd758e236... where two separate sets of DST affecting 13 years and dates as recent as 1960 have been obilterated. Where is the discussion of this specific (huge) change? Where is the justification?
That there is very good data for a lot of pre-1970 timezones is a fact, but the blocking of updating that information has been flagged before. We NEED an historically correct set of data which I had thought that was now accepted, but it seems not? If tz is not going to provide a usable table of data for pre-1970 data then one again we need to provide an alternative ... That some current materials provenance is suspect does not remove the need for something stable which flags that timezone/daylight saving was in place is still needed. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
