Ah, ok. But then he should subscribe to the mailing list while he is asking
questions of the list or the newgroup. Ie, expecting people to privately
email him answers to questions which he asks in public is not a good idea.
It deprives others of the benefit of the answers ( or of the benefit of
having the mistakes in the answers pointed out by other more knowledgeable
people.)

Just to amplify, Under Linux, BSD and others, the crucial file in something
called 
tzdata.
ftp://elsie.nci.nih.gov/pub/tzdata*.gz
which can be downloaded from the web. In that file are listed all the known
time regions together with their DST rules.  They update it about 10 times a 
year, every time they become aware of some new time zone information from 
somewhere in the world. Compiling it with zic, installing it,
and pointing your system to the appropriate file is all you need. That will
handle all changes like DST automatically with no intervention needed.

Under Windows, I do not believe any such structure exists, and you have to
persuade Microsoft to publish a patch for your system which contains the
info. But I may be wrong. Under Mac, I think that they also use the tzdata
database to handle time, but again I could be wrong. 
Thus his telling us what OS he uses would enable more helpful answers to
be given.
