A position measurement system is provided to determine a time difference between a first event and a second event. Position values are hereby determined from an individual periodic signal or from a plurality of periodic signals, wherein a first position value is determined using a measurement signal evaluation means when a first event occurs, and a second position value is determined using the measurement signal evaluation means when the second event occurs. The time difference is determined from the first and second position values. As a result, the time difference can be measured between two events with a high temporal resolution, with a reduction of electromagnetic interference caused by the time measurement.
