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 accommo-
date 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

and press
Enter. You

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.
