Looks like its for outside or stair lights to me.
Are they still working ?
Turn that switch off ABOVE the timer.
Do your lights stop working now ?
Once off grab the metal part of the timer and pull it out.
Switch the switch back on if needed and if the clock is still making a noise hide it somewhere.
