Setting the Real-time Clock
If your system has a real-time clock, it automatically keeps track of the time and date. This kind of clock is backed up by a battery so it keeps running even while the computer is turned off.
The MS-DOS TIME and DATE commands, as well as many software packages, display the time and date held in the clock, but they cannot make permanent changes to the time and date settings.
Use the Real-time clock option if you need to change the time and date permanently. For example, you may need to change the clock to accommodate seasonal adjustments, such as daylight saving time. Your computer automatically adjusts for leap years. Note that even though MS-DOS and your applications programs may use a different format, the real-time clock uses a 24-hour time format to store the time.
To set the real-time clock, follow these steps:
1.On the main menu, press 1 to move the cursor block to Real-time clock and press Enter. The time and date appear like this:
19:45:55 -
1@21-1987 Date
2.To set the time, move the cursor to Time and press Enter. You see:
I”:“:“”
Enter the time in the exact form shown in the box, using two digits for each part; the program automatically inserts the colons (:).
When the time is correct, press Enter. If you enter an invalid time, the computer beeps, and the time does not change.
