I'm not convinced this belongs in this repo, and I'm not convinced by the interface either. Bad ChatGPT, bad!

Seriously, I would much rather make interval changable via reset() in the current timer, and build something on top of that instead of re-implementing the whole thing. All we need is a interval-reseteable timer and a container that gives you the next interval from a list of "scheduled timers", they can be completely decoupled.

If there is no such a container available yet, I would add it to https://github.com/frequenz-floss/frequenz-core-python/ instead.

What I envision is something like:

timer_scheduler = TimerScheduler()
timer_scheduler.add(...)

timer = Timer(timer_scheduler.next(), ...)

async for selected in select(timer, other):
    if selected_from(selected, timer):
        ...
        timer.reset(timer_scheduler.next())
    if selected_from(selected, other):
        ...
        timer_scheduler.add(...) # or timer_scheduler.remove(...)    
...

Well, I designed the interface and ChatGPT did a good job at it imo.
And I like it too.

What I envision is something like:

How would you propose to interrupt a scheduled timer that is currently in ready()'s await asyncio.sleep(..)?
Which task do we have to cancel?

I guess you already answer it for yourself with #320 :)
