with the game there is a small booklet that says
The Elder Scrolls III and the name Morrowind below it;
on page 45 there is a section called Resting and Waiting and it reads as follows
in the second paragraph : Waiting is helpful if you want time to pass more quickly until a certain hour (or perhaps a change in weather) Waiting only allows your Fatique to recharge,while resting recharges Fatique, Health, and Magicka, Also resting is the only way to level up.
Press T to rest. T = time. Press T and it will show you the time of day and ask you if you would like to rest and for how long,if you are in a legal sleeping area. Just do a little math and you can figure out how much time you need to sleep in order for the proper time your looking for. if you can't find a bed to sleep in just leave town and sleep by a tree then return to the town at the time you need to do the task.
