You are correct, the types in the documentation are not correct.

When you choose a very low resolution, the timeline might become very big. At least on Linux if I for example choose start=0, finish=10 and resolution=0.001, I get a BadAlloc error, indicating that not enough resources are available to create the widget. I don't know how the program will behave on Windows when this happens.

However, the exact limit might depend on a number of factors, which would have to be derived from the actual Tk code. In the past I have run into issues when using more than 16MiB of video memory, for example, but it depends also on configuration, OS, etc.
