Epson 486SX - Manual (Page 52)

Follow these steps to set the real-time clock:
1. At the main menu, highlight Real-time clock. If the
time and date have been previously set, the current settings
appear:
Time 0 9 : 1 6 : 5 2
Date 03-29-1992
If the time and date are correct, you can skip the rest of this
section.
If the time and date are incorrect, go to step 2 below.
If the time and date have never been set, the submenu
contains a template for you to fill in:
Time x x : x x : x x
Date xx-xx-xxxx
2. Press to move the cursor block into the submenu.
3. To set or change the time, press again. You see this
template:
hh:mm:ss
(“hh” stands for hours, “mm” stands for minutes, and “ss”
stands for seconds.)
4. Using a 24-hour clock, enter the time in the exact format
shown in the box. Type two digits for each part; the Setup
program automatically inserts the colons (:). For example,
to set the time to 1:30 p.m., you would type the following:
1 3 3 0 0 0
