A damping ring has been constructed at the middle of the linac to generate a positron beam with sufficiently low emittance to support a 40-fold higher luminosity in the SuperKEKB asymmetric collider over the previous project of KEKB, in order to increase our understanding of flavour physics. A timing and control system for the damping ring is under construction to enable the timing synchronization and beam bucket selection between the linac, the positron damping ring and the SuperKEKB main ring. It should manage precise timing down to several picoseconds for the beam energy and bunch compression systems. Besides precise timing controls to receive and transmit positron beams, it has to meet local analysis requirements in order to measure beam properties precisely with changing the RF frequency. It is incorporating the event timing control modules from MRF and SINAP.
