Done.

    [torvalds@g5 git]$ ./test-date "now" "midnight" "high noon" "tea-time"
    now -> bad -> Wed Dec 31 16:00:00 1969
    now -> Fri Nov 18 08:50:54 2005

    midnight -> bad -> Wed Dec 31 16:00:00 1969
    midnight -> Fri Nov 18 00:00:00 2005

    high noon -> bad -> Wed Dec 31 16:00:00 1969
    high noon -> Thu Nov 17 12:00:00 2005

    tea-time -> bad -> Wed Dec 31 16:00:00 1969
    tea-time -> Thu Nov 17 17:00:00 2005

Thanks for pointing out tea-time.

This is also written to easily extended to allow people to add their own
