The discussion on 'extended' timezones is still going on ;) Daylight saving did not start in 1970, but the recent proposed change in tz was to ignore them to simplify the list of timezones. That has now been reverted, but how to handle the additional information has not yet been agreed. The tz dataabse will probably not return pre 1970 date, you will need a different build of tz to get that. Which is something I think is simply wrong! We have increasingly accurate pre 1970 data but that requires additional timezone names which the basic tz database will not support. -- 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
