Just came across a source of articles about Time Zones and Daylight Saving Time from the perspective of Customer Service, or other staff dealing with them, across the globe, at NotAlwaysRight.com. The tone reminds me of articles in The Register. My attention was first drawn by a series of articles entitled "No Fortitude for Longitude" and I have attached some links to that series and to results from search queries on the topics. -- Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada This email may be disturbing to some readers as it contains too much technical detail. Reader discretion is advised.
