Yeah, this is the way JSON.stringify/parse works. We would need another serialisation scheme to support dates.

So the "proper" way to deal with this would be to rebuild the dates in the workers?

Yes, you need to recreate the date objects when you need them.

We are facing similar problems using date objects in our jobs. A nice solution could be to use superjson (https://github.com/flightcontrolhq/superjson) (or similar) to serialize and deserialize job data. This would automatically handle date objects and also bigint (#447) or map.
I think it should not be very difficult to implement. For us, as we use a lot of workers, it would be helpful to have a global option to always use superjson for all jobs.
