It's all solved now. The problem was the city set for the timezone does
not have DST at all, which is why the option doesn't appear. Also, I did
not mention the timezone I am in because (a) it's not my PC with the
problem, and (b) it didn't occur to me to be relevant anyway. I was
posting on behalf of someone else, and was getting them to replicate
your responses.
Thanks to all who replied. And believe me, the in-fighting in some of
the reponses are what makes Usenet so adorably wonderful.

Out.
