decimal dev rtc sec min hour day month year set-time

So to set the clock to 10 seconds past 11:15PM on December 31st, 2005, the command would be:

decimal dev rtc 10 15 23 31 12 2005 set-time

0 > dev /bandit/ohare/via-cuda/rtc  ok
0 > . . . . . . decimal get-time 1907 6 5 1 8 58  ok

0 > dev /bandit/gc/via-cuda/rtc  ok            
0 > . . . . . . get-time -559038737 6 23 10 57 31  ok

0 > . . . . . . get-time -559038737 6 23 10 57 31  ok
0 > decimal 31 57 10 23 6 0 set-time  ok
0 > . . . . . . get-time 1991 6 23 10 58 56  ok

1. rtc PATH is not fixed machine by machine (but may always be under via-cuda/rtc)
2. to get time current setting, use . . . . . . get-time
   (do twice to get real number)
3. have delay to be effective (see above)
4. offset 0 0 0 2 2 1813
