    • setLocalLastUpdated

      public UpdateCheck<T,E> setLocalLastUpdated(long localLastUpdated)
      Sets the last-modified timestamp of the corresponding item produced by a local installation. If non-zero, a remote update will be surpressed if the local item is up-to-date, even if the remote item has not been cached locally.
      Parameters:
      localLastUpdated - The last-modified timestamp of the corresponding item produced by a local installation or 0 to ignore any local item.
