Correct.  You can't get *the* timezone.  You can get the possible  
timezones, on the basis of the Accept-Language header.

Yes, that's a reasonable solution for some apps, and generally a good  
approach to remember.  As you said, though, it's difficult to do it  
in a non-hacky, general way.  On the other hand, I might like to see  
if I can use the trick to have a timezone widget do a better job of  
finding an initial value.
