Request for Timezone information

[Doug McKenzie]

Would someone please post or email a good list or pointer to a list of which
countries use which timezones, and how daylight savings is implemented?  I
have a decent atlas, but it doesn't even try daylight/summer switches.

I've heard of an "Arthur Olsen" approach to unix timezone information,
but don't know where to find it.

Apart from sys V's /usr/lib/tztab, The only source I have so far for
daylight switches is an astrology book!  But it's old and has lots of
errors.

Thanks!!
