Spiral time was a 2am idea for a fancy watch and has nothing to do with spirals. Hours go from 0 up to 12 and back down to 0. Minutes and seconds go from 0 to 30 and back to 0. Pyspiral can convert to spiral time and also has a graphical clock.
For any datetime:
from datetime import datetime
from pyspiral import spiraltime
someTime = datetime.now()
print spiraltime(someTime)
Output: ↑00:↑03:↓23
(at 12:04:36 am)
As a shortcut for the current spiral time you can use spiralnow()
To display the graphical clock:
from pyspiral import SpiralClock
x = new SpiralClock()
x.run()
