I've merged Yasser's PR (thank you!), but in the review discussion for that, we noticed something else: the `total_seconds()` documentation mentions the floating point dynamic resolution problem, but doesn't mention using `//` or `divmod()` as the fix for that, while the operator table doesn't mention the dynamic resolution problem at all.

So I haven't closed the issue yet, as fixing that feel in-scope for this issue, even though I didn't want to hold up the initial PR for it.
