WebbThe implementation of the hrtimer based periodic tick is designed to be extended with dynamic tick functionality. This allows to use a single clock event device to schedule high resolution timer and periodic events (jiffies tick, profiling, process accounting) on UP systems. This has been proved to work with the PIT on i386 and the Incrementer ... Webbsteady_clock是没有to_time_t()的实现的，而system_clock是有的。 high_resolution_clock实际上和steady_clock一样。一般使用场景是： system_clock：用在需要得到绝对时点的场景; steady_clock：用在需要得到时间间隔，并且这个时间间隔不会因为修改系统时间而受影响的场景 ramsay estate

Webb17 aug. 2024 · Below 100ns not even spin locking can really match the requested time well, probably because calling high_resolution_clock::now() takes about 100ns on my system. I have to admit it’s a bit difficult to tell how the different sleep function compare at higher times here because the errors are so miniscule.

WebbThe cause of this issue is that CentOS 7's libstdc++ uses syscall `SYS_clock_gettime` rather than glibc's `clock_gettime` for `std::chrono::system_clock::now` and `std::chrono::high_resolution_clock::now`. The syscall one is much slower than the glibc onc since the glibc one does not need to invoke a syscall usually.
