The ath5k and ath9k drivers do so. If a driver/hardware don't, it cause=
s other problems. For example ("iwconfig wlan0 essid new_ibss") if the =
sync isn't done before the first beacon is send and the TSF of the old =
IBSS-Network was higher the the TSF of the new one, so the all nodes of=
 the new network now sync to the higher TSF of the old network.
