Abstract: A system and method of inputting time on an electronic device having a touch screen that displays a graphical hour keypad and detects user touch input to select an hour from the keypad, and displays, either simultaneously with the hour keypad, or following selection of an hour, a graphical minute keypad and detects user touch input to select a minute from the keypad. The selection could also be done in reverse order. The hour keypad can include one 24-key keypad or two 12-key sub-keypads and the minute keypad can include one 60-key keypad and/or one 12-key keypad. If the 60-key minute keypad is not used, the user can enter a minute that is not a multiple of five by using a standard 10-digit numeric keypad, incorporating movement events or pull events, or causing a sub-keypad to be displayed. A slide gesture can be employed to select both hour and minute.
