Typescript: Internal types use Date instead of NativeDate - bug?

[kfiroo]

Hey!

Trying to implement custom timestamps.currentTime as described in the docs

My simplified implementation looks like this:

const thingSchema = new mongoose.Schema({
  //...
}, {
  timestamps: {
    currentTime: () => new Date()
  } 
});

I get the following TS error:

TS2322: Type 'Date' is not assignable to type 'number | Date'.
  Type 'Date' is not assignable to type 'number'.

After some investigation it looks like there might be some confusion with the NativeDate and Date types.

For instance, I would expect mongoose.now to return NativeDate and not Date
Same for mongoose.SchemaTimestampsConfig.currentTime.

mongoose version 5.13.2

tsconfig.json

  ...
