问题如下:

    time: 21/6/9 11:3371000000                                                                                                               二:打印RMC时间21/6/9 11:3371000000
    lidar: data_type:2 ts_type:3 timeStamp: 21-6-9 11:3356419917                                                         三:将当前时刻的点云时间戳打印出来   点云输出时间 21-6-9 11:3356419917    (两者相差了将近15s)

    OnLidarSetRmcSyncTimeCallback statue 0 handle 0 response 0.


疑问:为什么UTC的时间没有更新到输出的点云上,并且时差很大,希望能得到你的回复,谢谢!
