Can I change SlowPar of an object?

Hello, how can I access and change SlowPar parameter (Object->Anim settings) of an object with python? Is it possible?

(scroll down to 'timeOffset)

NOTE: The site says it apparently doesn’t work with the parent actuator so the parent-child relationship apparently must be there at the start of the game.

Thanks, it is what I needed
