question: public static int compare ( UUID uuid1 , UUID uuid2 ) { int timeResult = Longs . compare ( uuid1 . timestamp ( ) , uuid2 . timestamp ( ) ) ; if ( timeResult != 0 ) { return timeResult ; } return uuid1 . compareTo ( uuid2 ) ; }
target:  Compare two time UUIDs deterministically, first by their embedded timestamp, next by their node-specific sequence number, finally breaking ties using their embedded node identifier.\
