Looking at the source of getdate() it strikes me several 'foreign' pointers are used before being checked. From this I suspect there is something wrong with the timezone settings on my machine.

Yes, installing the timezone data fixed the problem! This still leaves the pointer checking issue so the user simply gets no data or an error message :-)
