wander

v. loiter; move aimlessly; lose one's way; go astray

In telecommunication, wander are long-term random variations of the significant instants of a digital signal from their ideal positions. Phase variations with a frequency content above 10 Hz are considered jitter, while those with a frequency below 10 Hz are referred to as wander.[1]  Wander variations are those that occur over a period greater than 1 s (second).  Jitter, swim, wander, and drift have increasing periods of variation in that order.
