In ground-based extensive air shower experiments, the direction and energy are reconstructed by measuring relative arrival time of secondary particles, they deposit. The measurement precision is crucial for determination angular resolution. For this purpose, we need to obtain a precise offset each detector, apply calibration process. associated with photomultiplier tube, cable, relevant electronic circuits, etc. view transit through long cables being heavily dependent on ambient temperature, real-time method cable investigated in paper. Even poor-resolution time-to-digital converter, can achieve high precision. This has been successfully demonstrated Front-End-Electronic board used Daya Bay neutrino experiment.
