When the NativeDateAdapter clones a date, it creates the clone only from the year, month and day which means that the clone's time will be different from the source.

For some reason in google3 it complains about Argument of type 'Date' is not assignable to parameter of type 'string | number'. Instead maybe you can do new Date(date.getTime())
