Clock programming instructions?

Hello,

I own a 1989 Grand Marquis (what else!) and do not know how to set the clock and other features of the trip computer etc.

I'm wondering if anyone can help me out?

Thanks!

Is this the clock with the 3 buttons on the bottom, Time, Etime, and Date?

To change the time, you have to press the time button on the bottom, then press the black button on the upper right, this will change the hour. The black button on the left, while the time button is pressed will change the minute. Basically the same principle to change the date. But I don't know anything about the Etime button.
