March 13

Assuming you are referring to daylight savings time, the clocks already changed at 2:00 am on Sunday March 13, 2010.

There is a book called "Room 13". The funniest of all books with 13 in the title has got to be Thurber's The 13 Clocks.

Howard Miller Clock Company offers a wide range of clocks, including wall clocks, mantel clocks, floor clocks (grandfather clocks), table clocks, and atomic clocks. They also offer specialty clocks like chiming clocks, musical clocks, weather clocks, and indoor/outdoor clocks.

You can stop the clocks by not worrying about the clocks.
