Time zones and daylight saving arrangements in particular are a nightmare at the micro level. I once worked on a large customer support application which required all dates/times to be viewable in UTC plus any of: - The local support centre's time (eg. Tokyo, Japan) - The customer organization's local time(eg. Seoul, Korea) - The local site time (some remote island in the pacific...) The big problem was the last one since some small countries have local arrangements for timezones that don't conform to the official ones. One pacific island had dual "patrons" and to avoid offending either they adopted a non-standard "timezone" half-way between the two patron's zones! In another case we had the principality of Andorra deciding to put off switching to DST for an extra week because it would make the snow melt faster and spoil the skiing! This was decided by the council on the Friday before it was due to happen and announced on the local radio... I got more grey hairs on that project than any other. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos -- https://mail.python.org/mailman/listinfo/python-list
