The DABS sensor timing subsystem, which consists of two clocks driven from a common station standard, is the subject of this paper. The subsystem configuration is described and the rationale for this design briefly given. Emphasis is on the techniques for synchronization to an external standard, coordination with other sensors and system restart after a failure or deliberate shut-down.
