Superconducting nanowires single photon detection (SNSPD) is considered as a technology with excellent comprehensive performances. In particular, its excellent temporal resolution makes itself possess a wide application in the fields including quantum precision measurement and time-varying astronomical observation. In this paper, from three aspects of heat cycle, electrical cycle and time jitter, we reviewed the influence factors of temporal resolution and underlying physical mechanism, intrinsic limits, and possible optimization directions in SNSPD. In addition, we introduced the recent temporal resolution works related to X-ray SNSPDs in our group. The study in SNSPD is helpful to disclose the internal physical mechanism of the SNSPD technology and shows some value in the practical engineering application related to time measurement.
