This calculator requires the use of Javascript enabled and capable browsers. This creates and displays the time (local to your time setting) in either 12 or 24 hour format, your choice, in a live accurate clock. By selecting either the 12 or 24 designator, and highlighting it, the time will change from 12 hour (AM or PM) to 24 hour format, or in reverse. The time is based on YOUR computer's time; therefore the accuracy of this clock is a reflection of the accuracy of the time on your computer.
