DatetimePicker is a roulette based datetime selector like in iOS and android.

The only immediate dependency is the garden package kivy.garden.roulette. However, if you have never installed garden packages before, and start with only a default kivy python distribution, then the following garden packages are needed. Use garden install to install them.

a. kivy.garden.tickline

b. kivy.garden.roulette

c. kivy.garden.roulettescroll

Just instantiate DatetimePicker()

if __name__ == '__main__':
    from kivy.base import runTouchApp
    runTouchApp(DatetimePicker())

This will give you 6 vertical roulettes that respectively represent year, month, day, hour, minute, and second.

DatetimePicker.selected_value records the selection from the user.

DatetimePicker.density controls how many values are shown at a time.

I didn't focus much on the graphics, or to closely simulate the iOS or android experience. You are encourage to contribute to improve the default appearance of the datetimepicker!
