We already have the `getTiming().localTime` member. I wonder how this should interact. Should we set it through `updateTiming()` instead?

This seems reasonable (assuming we have a natural means of extending this to do nesting in future).

Sounds great.

This seems reasonable to me but we'll need to think about how we expect this to be updated in future.
