Well, this thread obviously attracted a lot of interest. ;) In any case, I have now completed WindowsTimeZone, so the last item which was not completed is now complete, and the entire module should be complete. Now it's just a matter of whatever tweaks are necessary to get it into Phobos.
The most recent code can be found here: http://is.gd/go6Co Again, changes.txt includes the changelog, Doc holds the ddoc generated html files (which now follow the Phobos style sheet), and Src holds the Src files. datetime.d is the module with the date/time code, and unittests.d holds code to help with unit tests in datetime.d. - Jonathan M Davis P.S. When building datetime.d on Windows, you must now link in advapi32.lib, because that's the dll that holds the functions for reading the registry.
