nodiscard

计算两个时间戳之间的时间差。 Computes the time difference between two timestamps.

Parameters

old_millisecond 旧的时间戳。The older timestamp.

Returns: Duration 计算得到的时间差。Computed time difference.

Definition at line 103 of file libxr_time.cpp.

{
  uint32_t diff;  // NOLINT
 
  if (millisecond_ >= old_millisecond.millisecond_)
  {
    diff = millisecond_ - old_millisecond.millisecond_;
  }
  else
  {
    diff =
        millisecond_ + (libxr_timebase_max_valid_ms - old_millisecond.millisecond_) + 1U;
  }
 
  ASSERT(diff <= libxr_timebase_max_valid_ms);
 
  return Duration(diff);
}
