The whole basis of the tzdist setup was that it provides a distributed means of serving the data. At the top level there is a need for primary publishers and since IANA *IS* a primary source then that material does need to be published somehow. The ONE think that is important here is that any publisher should properly identify the range of data that it is providing in addition to being able to service the differences between the current version of a rule set and that the client is actively using and any later changes. TZDIST is not simply a means of serving a single view of the TZ data, it is intended to be able to also provide an indication that the rule set that was used initially to normalise data has now changed. Bypassing that mechanism by only providing a current monolithic dump of the data is not what was intended and is why it is based on individual timezone identifiers, and each can be developed separately as further historic material becomes available. We need to at least start to build the seeds of publishers but personally I'm not sure IANA is the right starting point since TZ is already a truncated data publisher ... -- Lester Caine - G8HFL ----------------------------- Contact - https://lsces.uk/wiki/Contact L.S.Caine Electronic Services - https://lsces.uk Model Engineers Digital Workshop - https://medw.uk Rainbow Digital Media - https://rainbowdigitalmedia.uk
