menu you can select the time for many cities around the world.
The center top group of buttons are numbers and arithmetic operators.
The buttons on the right and bottom are common scientific calculator buttons.
The left bottom group of oval buttons either bring up a new set of functions, or do units
conversion. To find out what a button does, move the mouse cursor over it and a tool tip will
appear describing the button's function.
