DST and OS software

[Chris Carrier]

Which is why daylight saving time rules should NOT be incorporated into
OS software -- because they continually change.  I am wondering how many
computers in the European Union (except UK/Ireland) went back to standard
time September 29 when the EU didn't fall back until October 27, the former
date being programmed into them when the code was written because the last
Sunday in September was the rule then.
