Everything You Could Want for a Desktop Clock
I am using an IMac, Lion 10.7.3 You can drag the clock to anyplace you want on the desktop. By clicking twice on the clock the Prefernce Menu appears. Here you can resize the clock, select the 12 or 24 hour format, select the style of clock from 20 different ones, select the super lite option, if you wish you can have the clock always float on top, and opt to have it start on log in. You can also have it show up on the status bar. I give it 5 stars.
