As already stated, some devices such as central heating controllers would not need a processor capable of the sort of processing power needed to handle that, but would benefit immensely simply from switching DST setting at the right time. If that needs a 'son of tzdist' specification then OK but it's those sorts of devices that the 'NOT' requirements of the charter are directly addressing? Given that the sort of processing power available today is probably making that a thin argument, but a substantial number of 'internet ready' processors do not have a large spare storage capacity even given how small the TZ database can be compacted ( and don't have leap-second capable clocks ;) ) many of these are already active on the internet. -- 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 _______________________________________________ ietf-privacy mailing list [email protected] https://www.ietf.org/mailman/listinfo/ietf-privacy
