The Apple IIGS has a built-in calendar/clock that runs from a battery rather than from the power supplied to the computer, so it keeps accurate time even when the computer is switched off. You shouldn't have to set the clock very oftenexcept to make adjustments if you live in a place that observes Daylight Saving Time.
Follow these steps to set the computer's calendar and clock:
1. Choose Control Panel from the Apple menu.
