1. Enter the required data immediately following the colon (:). If
you are using a3210 or a supported CPU display console,
enter the information in the user input area. The information thenappears in the output display area on the line fclloving the SET TIME r.equest.
2.You should enter a time value that is some 30 to 60 seconds ahead
of the currenttime, because CP requests you to press the TOD ENABLE SET switch when setting the clock.
Forexample, if the date is 03/01/14, and the time will soon be 08:28 (EST), the exchange on a printing terminal looks like this: VERSION 1 LEVEL 0 mm/dd/yy SET DATE 88/DD/YY :03/01/14 SET TI8E HH:88:SS :08:28:00 PRESS "TOD ENABLE SET" KEY AT DESIGNATED INSTANT When you press the TOD ENABLE SET key, CP responds with: NOW 08:28:00 EST FRIDAY 03/01/14 CHANGE TOD CLOCK (YESINO): !Qte: The previous example executed on a display terminal would show
your responses on separate lines.You now have an opportunity to change the value of the clock. If you
enter "no", or press theEND function key on the console, clock
initialization ends. If you enter "yes", another series of promptingmessages permit you to enter a new date and time. To V8/310 users, the epoch clock value of all zeros
indicates the beginning of the day January 1,1900. To OS and OS/VS users, the epoch clock value of all zeros represents the beginning of
the day January 1,1960. Thus, OS virtual machine users will find that
stored clock values differ by60 years; however, it is possible in OS to
use1900 as the base epoch clock value.
