I CAN see a case for storing the version of tz used along with the timezone
Absolutely, if one is serious about provenance. One should record the tz database version (including local changes and options) as part of the provenance. One way to record this sort of information is OPM <http://openprovenance.org/>. The tz database version is only a part of this problem, as in the typical case one also needs to record the C library version, kernel version, hardware version, etc.
The problem is getting distributions to stop messing the version number up :( PHP's getversion is returning garbage on some distributions ... -- 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
