This paper describes the tests done for validating the timing accuracy of the GEO 600 data acquisition system. Correct time stamping of the recorded data is required for a number of search algorithms for gravitational wave signals (coincidence analysis, targeted pulsar searches, etc). Tests on the current system determined the absolute timing offset to be 15.89 mus with a standard deviation of 63 ns. Both offset and jitter were measured against an external reference clock. Additional analysis of data recorded during the S I data taking run was done to validate the timing accuracy during this period.
