Abstract
We summarize the detail design of the timing system of newly born X-ray satellite XRISM, including both onboard instruments and off-line data-processing tools. The absolute timing accuracy of 1.0 msec is required for the system. We also report the results of both the ground timing test and in-orbit verification observation using a millisecond pulsar on the timing performance of the XRISM timing system in the nominal operating mode, i.e., assigning time stamp using the GPS signals from the GPS receiver onboard the spacecraft.
