psdk v2.1.1 时间同步
Completed
使用psdk v2.1.1和m300 rtk进行时间同步，遇到时间同步不上，里面的local:391647042000,时间是不是飞机上的时间？然后trigger:60680554是我收到pps信号打的时间戳。我发现我同时订阅收到数据的时间戳和local时间戳差了很远，数据的时间戳：timestamp: millisecond 360623 microsecond 360623658.
同时我已经注册了GetNewestPpsTriggerLocalTimeUsCallback函数，从报错中也可以看到，psdk已经拿到了我设备打的pps时间戳

如果我把系统时间设置为从0开始和使用utc时间的结果是一样的。
遇到的文问题和这个很像，基本一模一样：https://sdk-forum.dji.net/hc/zh-cn/community/posts/4403239564953-PSDK%E6%97%B6%E9%97%B4%E5%90%8C%E6%AD%A5%E5%A4%B1%E8%B4%A5
还有一个问题，订阅的数据如何做高精度的时间同步，订阅数据时返回的时间timestamp，能否通过返回值pps同步的时间计算差值来实现？
