Yea, would guess transmission issues from the rocket to the ground and the clock is added on the ground somewhere. I wouldn't expect the clouds to interfere if the transmission went up to space then back down (would expect them to do something like that at some point). But maybe microwave from ground to rocket could have had clouds interfere with the signal?
