In order to load the custom class loader, the runtime must verify the signed JAR first, and the algorithm constraint code tries to load a `Locale` provider using a `ServiceLoader` before the class loader is set, and this causes a `ServiceConfigurationError`.

Instead the `ZonedDateTime` API is now used, which simplifies the code and removes some unnecessary code from `keytool` as well.
