Could DATE be already defined somewhere else? In a system header file, perhaps?

Try renaming your class to something more likely to be unique (e.g. zakk_DATE) and see if the problem persists.

Conventionally, names in ALL_CAPS are preprocessor macros. Maybe you should check the preprocessed output of your compiler -- this could help to diagnose in the case there is a macro collision. For GCC-compatible compilers, the flag is -E.
