      Returns:
      last modified time, to nearest second

    • forceInvalidationEvent

      Forces an invalidation event. This is required in a rare case, to clear out a StreamableResource generated from the component message catalog; there are some walls in place that prevent the message catalog's underlying Resources from being exposed.
