I think iirc that at-at uses scheduledexecutor and is a very simple and stable library which only does one thing, but does it well and has no feature requests. I wrote schejulure which does a very similar job but with cron style time specifications rather than periodic and haven't touched it for years because it just works and even though it's used in production nobody has found any issues or needed it to do anything it doesn't already do. I think the same is probably true of at-at.
