1. A method, comprising:
determining, at a first access point in a first wireless network, to monitor transmissions between a second access point and a computing device, wherein the computing device performs time synchronizations with the second access point in the transmissions using time measurement exchanges;
detecting, at the first access point, a particular time measurement exchange between the second access point and the computing device, wherein the particular time measurement exchange indicates a synchronized time between the second access point and the computing device;
determining to perform a time synchronization with the computing device or the second access point; and
performing the time synchronization with the computing device by synchronizing a first clock of the first access point with a second clock of the second access point or the computing device.
