A system and method for configuring time related settings using a graphical interface is presented. A user is able to configure a time-of-day and select a time zone on an electronic device using a maximum of two stylus movements. The user contacts a display with the stylus and makes an hour stroke and minute stroke in one motion, without lifting the stylus from the display. The user may adjust a time value by moving the stylus in a clockwise or counterclockwise direction. When the user is satisfied with a time value, the user removes the stylus from the display. If the user wishes to toggle an AM / PM indicator, the user performs a toggle stroke to instruct processing to change the AM / PM indicator. Processing also identifies a time zone corresponding to a radix point which is created during the hour stroke and minute stroke generation.
