Make _convert_time public and add funtionalities

🚀 Feature Request

Allow Time conversions

Motivation

For custom callbacks, it would be nice to expose _convert_time in the API.

Hopefully, it is expose _convert_time in the API. That is _convert_time -> convert_time. And add the conversion type.

I am happy to start a PR about that

Agree! This would be helpful. If you want to open a PR, that would be great. I think it'd be useful to have a state function that exposes this functionality?

[priba]

I thought on moving the function to core/time.py. What do you mean by state function?

[mvpatel2000]

I thought on moving the function to core/time.py.

core/time.py is only classes, so it might be simpler to just leave definitions there.

What do you mean by state function?

Instead, I was thinking of attaching this as a function to class State in core/state.py. The signature would change to no longer take a state as an argument and just use self instead.
