> Maybe I'm misinterpreting what you wrote but the test fails before the patch and succeeds after it so what's the point in adding multiple tests with different timeouts?

Well, the test you added tests explicitely for a value < 1s because
this specific bug was due to a rounding error, but I think it could be
interesting to check a couple more values, within a reasonable range
(not too long).
It's just a matter of calling it in a loop, but if you don't deem it
necessary, that's fine with me.
