The present invention relates to a kind of clock system and method, belong to technical field of geophysical exploration, be specifically related to a kind of VSP during drilling and measure clock system and method.Including: ground synchronous device, underground synchronous device, energy source synchronizer.The present invention sends synchronous averaging or the unlatching of end signal control downhole instrument and stopping in whole moment second;By the time of recorded downhole with ground timing as reference, thus eliminate time error;Further, ground accurate clock is delivered to down-hole by time data carrying device by the present invention, it is possible to the timing error that correction VSP clock produces because of its Long-term stability difference under the hot environment of down-hole.
