You speed up one or both clocks to get them to strike midnight (both hands straight up) at more or less exactly the same time. Placing your mouse cursor over either one of the clocks will speed it up, and it will run faster for a few seconds after you move the cursor away.
In Detail
In the third floor bedroom (left) there are two clocks on the mantelpiece. They are spinning separately, and every time one of them hits midnight (both hands straight up), a skeleton springs out. According to the ghostly telephone in the room, the "light" will be revealed when the two clocks strike midnight at the SAME time. ("Darkness fills the grave. Find our light when midnight strikes twice.")
To get this to happen, you have to speed up one of the clocks by clicking on it, and then (if the midnights don't happen at about the same time) click on the other to speed it up. The problem is that the clocks continue to spin faster for awhile after you click, so timing the midnights is difficult. The best chance for success is to let one spin slowly, and when it gets close enough to 12 midnight, race the other one to catch it.
This is time-consuming but eventually the clocks hit 12 closely enough and they stop, revealing the LANTERN in the fireplace below. (Although you have the lantern, you still need to go to the basement to add kerosene to it.)
Placing your mouse cursor over one of the clocks makes that clock speed up.
Answer the phone it will say, "Darkness fills the grave. Find our light when midnight strikes twice." Click on the two clocks on the fireplace. When you click either one of the clocks, it goes faster for awhile. Time it so that both skulls pop out at the same time, which would be when both clocks hit midnight (both hands up)at the same time. When you have done that, the fireplace will open revealing a lantern.
