ChatGPT provided some helpful answers on how to accomplish this: https://chat.openai.com/share/a9811e15-29df-462a-9134-b7b231d79133
It also seems like FreeBSD, as of the 13.2 release, also supports timerfd: https://www.freebsd.org/status/report-2023-01-2023-03/#_native_linux_timerfd
Use case
It would be preferable not to have the scheduler overshoot the next schedule due to the host computer being suspended.
