这个可能是闰秒的问题,我们audit使用的是v0.3.6的specification和对应的driver,最新版本的specification里IC7的定义里有一些对于闰秒的修正:

Validation rule: Depending on whether the system-under-test supports leap seconds or uses UTC-SLS (UTC with Smoothed Leap Seconds), a difference of 1 minute can occur between the minutesLatency results of two correct implementations when the time interval includes June 30, 2012, when there was a leap second. Therefore, the minutesLatency value is validated using a tolerance of 1 minute.

如果照这个描述,看起来这些diff都在1分钟以内,是能够接受的(但那个版本的driver还是判错了)

能否麻烦你提供一下你的10g数据及正确结果的生成方式呢?谢谢
我们想尝试复现一下这些报错,针对错误日志,也可以确定是否为闰秒的问题
