StackOverflow 有人提供了一段 code:

public static String reorderTimeUUId(String originalTimeUUID)

    {

        StringTokenizer tokens = new StringTokenizer(originalTimeUUID, "-");

        if (tokens.countTokens() == 5)

        {

            String time_low = tokens.nextToken();

            String time_mid = tokens.nextToken();

            String time_high_and_version = tokens.nextToken();

            String variant_and_sequence = tokens.nextToken();

            String node = tokens.nextToken();



            return time_high_and_version + '-' + time_mid + '-' + time_low + '-' + variant_and_sequence + '-' + node;



        }



        return originalTimeUUID;

    }

def getTimeUUID(uuidVar)

    # ref: http://stackoverflow.com/questions/8713873/is-python-uuid1-sequential-as-timestamps

    import uuid

    if not isinstance(uuidVar, uuid.UUID):

        uuidVar = uuid.uuid1()

    tmp = str(uuidVar)



    tokens = tmp.split("-")

    if len(tokens) == 5:

        time_low, time_mid, time_high_and_version, variant_and_sequence, node = tokens

        return time_high_and_version + '-' + time_mid + '-' + time_low + '-' + variant_and_sequence + '-' + node

    return tmp
