Any idea how compatible that is?  Sure, it'll work with GCC's cpp, but  
we try to work with a huge variety of compilers.

At the very least you might want to wrap it all in #ifdefs or something:

#if defined(__DATE__) && defined(__TIME__)
/* your version */
#else
/* old version */
#endif

(Or play fun tricks with #ifndef ... #define, but then you also have  
to play with the format string or something.)
