RC: for NTP server updates more often

  This will be used for the Royal builds and will request an
  update from the server ever 15 minutes. If the request fails
  it will request an update every 10 mintues until a successful
  update.  Created VENDOR_IS_RC so our normal builds don't hammer
  the crap out of public NTP servers.
