Everyone likes clocks. In Windows Vista we can now add an additional two clocks to the system.
By hovering over the time we see the date and any additional times show up in text form. Or by single-clicking the time in the corner we can the familiar calendar and clock pop up.
Setting up the additional clocks is easy enough, just pick the time zone and give them a name.
If you really need more clocks you can use the sidebar gadgets, of which you could set a virtually unlimited number of clocks and have them available at the touch of a button on the sidebar, or even all over your desktop.
