  public static long getLongUUID()
  
  Unique number guaranteed if called with 0.01s minimum interval for 248.55 days. Don't call it frequently and don't use for things that may last 248+ days. For a long term UUID storage, make sure to check for collision first (32 bits from this UUID are securely random but it does not guarantee uniqueness)
