Description

 

/**
 * Generates an initial sessionId. High order byte is serverId, next 5
 * 5 bytes are from timestamp, and low order 2 bytes are 0s.
 */
public static long initializeNextSession(long id) {
    long nextSid;
    nextSid = (Time.currentElapsedTime() << 24) >>> 8;
    nextSid =  nextSid | (id <<56);
    if (nextSid == EphemeralType.CONTAINER_EPHEMERAL_OWNER) {
        ++nextSid;  // this is an unlikely edge case, but check it just in case
    }
    return nextSid;
}
