dateTimeConstructor property

@visibleForTesting @Deprecated('clients should not depend on this internal field') _DateTimeConstructor dateTimeConstructor

Allows specifying a different way of creating a DateTime instance for testing.

There can be rare and erratic errors in DateTime creation in both JavaScript and the Dart VM, and this allows us to test ways of compensating for them.
