Please bear in mind the following extract from the "Theory" file :- If all the clocks in a country's region have agreed since 1970, don't bother to include more than one location even if subregions' clocks disagreed before 1970. Otherwise these tables would become annoyingly large. __________________________________________________________________________ David Keegel <djk@cyber.com.au> URL: http://www.cyber.com.au/users/djk/ Cybersource P/L: Unix Systems Administration and TCP/IP network management
