Abstract:
A method for synchronizing time may include receiving initial time information including an initial timestamp from a first device, adjusting a clock of the device with the initial time information, storing the initial time information as an earliest possible time, receiving additional time information, including a second timestamp, from a second device, and evaluating the additional time information. When the evaluated additional time information includes information that is unacceptable, the method may further include adjusting the clock with the second timestamp, and replacing the earliest possible time with the second timestamp. When the evaluated additional time information includes information that is acceptable, the method may further include adjusting the clock with the additional time information, and replacing the earliest possible time with the additional time information. The initial time information and additional time information may be respectively determined based on reconciled time data received from two or more proximate devices.
