If you want more from your menu bar clock, then iClock Pro is what you have been looking for. You not only get the time and date, but also tons of other features like alarms, world times, a mini calendar, application run times, stock quotes, stop watch, moon phase and even provides floating clocks over your desktop if you wish. It is quite impressive and worth trying.
