In one aspect of the invention, a graphical user interface on a portable multifunction device with a touch screen display comprises: an hour column comprising a sequence of hour numbers; a minute column comprising a sequence of minute numbers; and a selection row that intersects the hour column and the minute column. In response to detecting a gesture on the hour column, the hour numbers in the hour column are scrolled without scrolling the minute numbers in the minute column. In response to detecting a gesture on the minute column, the minute numbers in the minute column are scrolled without scrolling the hour numbers in the hour column. The single hour number and the single minute number in the selection row after scrolling the hour numbers and the minute numbers, respectively, are used as time input for a function or application on the multifunction device.
