But that requires that you can force the file containing the macro to build every time - and there is no easy way to do that in DS:

I have a file that uses the TIME and DATE macros, but unless I make changes to that file or do a clean build, these values never get updated. If I right-click on a file in the project explorer and select properties, I can find an option to exclude the file from the build, but I can’t see anything for making sure it gets compiled every time.
