GenerateMessageId essentially gives unix timestamp, but in a horribly specific way Scheme of message_id (showed): |1-31|32-61|62|63| |A |B |C |D | Where: - A: Approximately equal curent unix time - B: Any random unique 30-bit number - C: Indicates the message initiator: 0 — for client-initiated (request or server response), 1 — for server-initiated (notification or client response to server request).
