Title: Require result parameter for JulianDate functions

1. Does not require a parameter for `fromXXX` and `clone`. (because that seems to be the pattern we are going with)
2. Used scratch parameters in places where it was easy to add.
3. I didn't try to optimize the Timeline widget since it's getting rewritten anyway.
