A fuel dispenser has internal fuel flow piping, a flow meter located along the internal fuel flow piping, and a displacement sensor operatively connected to the flow meter to generate information representative of an amount of fuel passing through the flow meter. The fuel dispenser also has a control system comprising a memory. In embodiments, however, the control system does not comprise a real-time clock. The fuel dispenser also comprises a synchronization module in electronic communication with the control system. The synchronization module comprises at least one antenna configured to receive a carrier wave modulated with synchronization information. Methods for obtaining accurate time information at the fuel dispenser are also disclosed.
