Claim:
1. A method for synchronizing a global time of an access point, comprising: receiving a message comprising a global time indication from a second access point, and updating the global time of the access point to the global time indication from the second access point by updating a timer of the access point by an increment not to exceed a predetermined value selected small enough to ensure a maintenance of synchronization between the access point and at least one associated wireless station, wherein when an anchor device is a common anchor device for the access point and the second access point, wherein updating the global time of the access point to the global time of the second access point is when a second difference is larger than a first difference, and wherein the global time of the access point is maintained if the second difference is smaller than the first difference, the first difference being between the global time indication of the second access point and a most recent global time received by the second access point from the anchor device, the second difference being between a stored global time of the access point and the most recent global time received by the access point from the anchor device.
