datatypes.Date to time.Time

## Your Question

In the documentation it talks about how to go from time.Time to datatypes.Date() - insert a time into database.

Reference:
https://github.com/go-gorm/datatypes/
https://github.com/go-gorm/datatypes/blob/master/date.go

But to retrieve a date from the database and convert to time.Time, I searched quite a lot and tried different methods to go from datatypes.Date() to time.Time.

I got this to work but I'm sure its probably not the best method.

```golang
x, _ := dbrecord.Date.MarshalJSON()
bDate, _ := time.Parse(time.RFC3339, strings.Trim(string(x), "\""))
```

## The document you expected this should be explained

## Expected answer

It would be good to have best practice in the readme on how to do this.
