I don't remember exactly off the top of my head, but this should at least get you started. Had to set mine this weekend after disconnecting the battery.
Hit the S/R key in the upper-right of the OBC (On-Board Computer) and then use the 1, 10, 100, 1000 keys to change the individual hour and minute digits. Once you have the right time displayed, hit the S/R button again to set it.
Hope that helps, but I was tempted not to respond at first out of sheer envy - it took me waaaaay longer than 3 hours just to replace the water pump when I first got the car!
