A Time-Date Sprite

[trlafleur]

This is a sprite that will display time or date formatted by Linux style "strftime"

     sprites:
       - DayTime: 
           x: 25 
           y: 10
           ticks_per_movement: 2
           dx: -1
           can_flip: false
           strftime: '%I:%M:%S %p'
           pallete: 
             text: 
               - 255
               - 0
               - 255
