If you don't tie any expectations to sending me code than I'm happy to
receive it and store it away in order to check it out when the time
has come...

>How about time()?

Good question :-)

@Michael: time() is the time-of-day function you were thinking
about...

After thinking about the pro's and con's for some time I decided to
implement time() simply by calling the appropriate ProDOS function.
The con's:
- Only available when running ProDOS 8 (not DOS 3.3)
- No seconds
THe pro's:
- Works with any clock supported by the currentl yrunning ProDOS
(either via built-in or loaded/patched driver

So a NSC *is* already used (at least indirectly via ProDOS) by the
cc65 C library.
