Hey @games, thanks for bringing this up.
Date/TimeOnlydo not support theIConvertibleinterface, so I'm afraid there is not much we can do about this.games commentedon Aug 24, 2025
Or maybe instead of using IConvertible , we should create a custom interface?

That would change hundreds of functions and i don't know how that interface would have to look like. Can you add implementations of custom interfaces to built-in types? If that works, would that require casting every input to that interface before passing it to the charting functions?
I'd love to review a PR that would not affect the current usage and add the desired support, but I am not sure if it is possible (feel free to prove me wrong though!).
