Unfortunately, there is one piece of information I have not be able to locate on any of the TimeZone-related resources on the Internet: - What is a good way to display time such that TZ info is absolutely clear. ISO 8601 falls short of this. For example, YYYY-MM-DDTHH:mm:ss-08:00 is insufficient because -08:00 is -07:00 in the summer and thus indistinguishable from Arizona which also uses -07:00. Adding the timezone makes sense, as in YYYY-MM-DDTHH:mm:ss-07:00PST Is there any standard for this or precedence on how this is handled in current (popular?) operating systems. Any other pointers? Finally, is there any program/script (for Linux, for example) that will display all the abbreviations based on the rules in the zone.tab and continent files? Just the most recent abbreviation will do. Such a program would eliminate errors when manually extracting zone abbreviations. Appreciate your response, --Raj
