Something that has a cutoff of 1970 will not be acceptable
The proposed 'backzone' file does not have a cutoff of 1970. Please see:
This is probably a discussion for tzdist ... My reading of the paperwork so far is that it is planned to have a full range base, and then sources that are supplying truncated data identify the fact, but what is not clear is how new historic data that identifies that a current timezone now has two historic routes. The planing seems to be based on tz zones, but as with all of these things there is no planning to manage tz identifiers. Can we not just describe 'backzone' as historic data. That the provenance of some material is 'poorly-sourced' just needs to be properly flagged within the file. The source comments forming part of the main files need to be reproduced in the history file to identify where data IS well sourced. I'm looking at the Jersey and Gernsey data there, but a quick scan on other historic entries which currently have no comments seem to have the source material in their main files? Hopefully what is then left is a better identified residue of suspect entries? -- 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
