I'm not that interested in resurrecting long dead data OK, in that case we can make the attic smaller, and use it more on a going-forward basis, with 2003d as the starting point. This will be a smaller change to the database now, which I assume is a good thing.
In which case we have to start setting up a second database as a home for the historical material that IS being used ... accurate documentation for daylight saving exist back to the 1960s, and presumably there is also a record of the confusion in the States prior to that? Certainly going back to diaries for calendars with pre 2000 dates should return the correct time. This was the area where I first found inconsistencies because of different rules being applied and our getting meetings moved an hour as a result! Moving back in time from that, getting the correct time difference between locations is equally important even if arbitrarily calculated for location, but where historic material does exist there should be SOME mechanism to combine that with the rest ... it was pulling the available data together that started the existing database and EVERYTHING gathered is important! -- 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
