Claim:
1. A method comprising: receiving, at a local device during a first communication window, a time value indicative of a remote device's view of current time, wherein the first communication window has a first duration during which communication signals can be communicated between the remote device and the local device to synchronize a frequency hopping sequence that is used for communication between the remote device and the local device; determining, at the local device, that the time value differs from a locally generated view of current time by at least an established amount; in response to the determination, establishing an extended communication window during which communications signals can be communicated between the remote device and the local device to synchronize the frequency hopping sequence that is used for communication between the remote device and the local device, wherein the extended communication window has a second duration that is longer than the first duration; wherein after establishing the extended communication window:
