Ah! I had thought it was just a "header file only" library. Whoops. That did fix the first problem. I tried switching to STLPort, and this time I copied the errors from the compiler. I guess that answers my question whether it was an STL specific problem. There is really no reason I have to use advance(), but I believe a model of Input Iterator should work with it.

This isn't the way to handle this. You will need to build and link the library (libboost_date_time). If you cd to libs/date_time/build and run bjam that will take care of it.
then the compiler started complaining when I tried to use std::advance.
is unfortunate that I do not have the exact error in front of me right now, but I did trace the problem to the definition of month_iterator. I found that if I derived its base implementation class from the class template iterator that it would compile without problems. Is this a problem with
STL that ships with MSVC6?
Unclear without the detail. The regression tests for MSVC6 do pass, so
It the there
is hope.
