Time Picker
When creating or editing an event you can choose the start and end time in three different ways (if "Settings", "Display and Use", "General", "Use improved time picker" is turned on):Plus/minus
The "Plus/minus" time picker uses the standard Android time picker which allows to tap on "+" and "-" buttons to increase or decrease the hour and the minutes. You can tap on the hour or minutes field to open a keyboard.
List
The "List" time picker allows to set the time with just two taps: Just choose the hour from the list on the left and the minutes from the list on the right.
Numberpad
The "Numberpad" time picker shows a number pad so that you can quickly type the time. Keys that cannot be used (e.g. because the hour can only start with 0 or 1) are automatically displayed in a darker color.
