有getSystemTimeStamp接口的Windows版实现方法么？

[wangwenfeng0]

/**

• @brief Get system timestamp
  */
  inline void getSystemTimeStamp(TimeStamp &timestamp)
  {
  struct timespec time1 = {0, 0};
  clock_gettime(CLOCK_REALTIME, &time1);
  timestamp.sec = time1.tv_sec;
  timestamp.nsec = time1.tv_nsec;
  }

/**

• @brief Get system timestamp
  */
  inline double getSystemTimeStamp()
  {
  struct timespec time1 = {0, 0};
  clock_gettime(CLOCK_REALTIME, &time1);
  return time1.tv_sec + time1.tv_nsec / 1.0e9;
  }
