(unless, perhaps, there is other information present from which you could infer such a value.) The difficulty then is that one has to decide up-front (i.e. when defining a vocabulary) how much precision is to be required if splitting out the different units as separate properties. I think goes against many intuitive approaches to representing information. E.g. you can't treat a VEVENT as a structure that can be extended/refined by adding yet more information: each property you add should in some sense increase the number of temporal situations thus described. It did occur to me that this is an argument for sticking with the ISO-based string representation of times. #g ------------------- Graham Klyne <GK@NineByNine.org>
