A time picker adjusts to a user’s preferred time setting, i.e. the 12-hour or 24-hour format.
A dialog picker is used to select a single time (hours:minutes) on mobile.
The selected time is indicated by the filled circle at the end of the clock hand.
Tap between the hour and minute label in the title bar to switch between the hour or minute view. Additionally, tap on the AM/PM label in the title bar to switch between AM or PM (in 12-hour clock mode).
The picker has a landscape view as well to suite the different screen orientations.
