I can't speak for Mr Mackin's direct experience, but I can most certainly contest the assertion that, "We in Australia have _never_ referred to DST as `daylight' time" - certainly everyone I know (and myself, of course) have always used the term "daylight savings" rather than "summer time".
Yes, we (Australians) certainly usually speak of "daylight saving" (or, with disputable correctness, "daylight savings"*) and "daylight-saving time", but we do _not_ speak of "daylight time"! All the examples and demonstrations given of the former are of no avail: they in no way support the assertion that Australians use or are familiar with the term "daylight time" or an abbreviation containing "DT" derived from it. "DST" is fairly likely to be understood, but not "DT". In my opinion, time-zone, or more accurately time-offset, abbreviation strings are a self-indulgent folly. I cannot really imagine what benefit they convey, in comparison to explicit numeric offsets, besides possibly indicating with unpredictable and widely varying granularity something about the accompanying data's location of origin and that location's time-offset history, all of which can be determined much more reliably and comprehensively by other means, and none of which is necessary to determine the time being represented in terms of another offset. Isn't determining the equivalent time according to another offset nearly always the _only_ purpose of time-offset abbreviation strings? And isn't that purpose fulfilled flawlessly by explicit offset indicators, something which time-offset abbreviations clearly do not do and cannot, judging by the intractable discussion on the subject, be expected to do anytime soon? It would seem to me that explicit numeric offsets should be compulsory, with offset abbreviations an optional indulgent addition to be regarded as no more than comment and ignored by software. My two cents' worth. --Alex ________________ * To be consistent with the terms "saving" and "savings" from economics, "daylight saving" would be the practice of saving daylight, whereas "daylight savings" would be what is saved, which in this case is hard to nail down, but might be considered to be an hour a day. _______________ Alex LIVINGSTON IT, Australian Graduate School of Management (AGSM), UNSW SYDNEY NSW 2052 Fax: +61 2 9931-9349 / Phone: +61 2 9931-9264 / Time: UTC + 10 or 11 hours It's year 2001, decade 201, century 21, and millennium 3 - the 1st year of the 1st decade of the 1st century of the 3rd millennium.
