Have you ever wanted a timer to help you keep on track? Well if you have a computer in your classroom, office, kitchen, etc. want no more. Online timer: http://timer.onlineclock.net/ has just what you are looking for. Time from a 5 second "test" to one hour, or anything in-between. An alarm goes off when the time is up. Just don't close the browser window while you are depending on it! Recommended by Gabe Oetjens.
