When transitioning current open TXG into QUIESCE state and opening a new one txg_quiesce() calls gethrtime(): - to mark the birth time of the new TXG - to record the SPA txg history kstat - implicitely inside spa_txg_history_add() These timestamps are practically the same, so that the first one can be used instead of the other two. The only visible difference is that inside spa_txg_history_add() the time spent in kmem_zalloc() will be counted towards the opened TXG. Since at this point the new TXG already exists (tx->tx_open_txg has been already incremented) it is actually a correct accounting. In any case this extra work is only happening when spa_txg_history kstat is activated (i.e. zfs_txg_history > 0) and doesn't affect the normal processing in any way.
