常见的存在的定时器问题 A)、部分定时器受clock set/NTP修改时钟的影响,导致定时器没有按时爆发 B)、没有处理好时钟翻转的逻辑,时钟翻转一般跟保存时钟的变量位数(比如16位、32位等)、保存时钟的精度(比如s、us等)、以及获取时钟的接口相关。 C)、还有其他长时间运行之后的异常。

Common timer problems exist A) part of the timer was affected by clock set/NTP modification clock, resulting in the timer did not explode on time B) the logic of clock turnover is not well handled. Clock turnover is generally related to the number of variables (such as 16 bits, 32 bits, etc.), the accuracy of clock preservation (such as s, us, etc.), and the interface of acquiring clock. C) there are other exceptions after a long run.
