Abstract. The EPIC-pn camera on board XMM-Newton provides a very high time resolution. In its Timing mode, EPIC-pn reaches a time resolution of 0.03 microsec and 7 microsec in the Burst mode. In order to monitor the relative timing accuracy, XMM-Newton performs two observations a year of the Crab pulsar. An automatic tool has been created to check the timing accuracy of EPIC-pn. It calculates the period of the Crab pulsar in the X-ray regime and compares it with the period obtained from radio data. Observations of pulsars PSRB0540-69, PSRB1509-58 and PSRB1055-52 have also been used in this analysis. We present first results of the timing accuracy from this analysis covering the whole XMM-Newton mission time till revolution 1000.
