Narrative:

We were cleared to 33000 ft. Due to incorrect altimeter setting on standby altimeter, autoplt leveled at 33200 ft. Aircraft was taken off autoplt and leveled at 33000 ft and correct setting put into altimeter. Error and correction took less than 5 seconds. No conflict occurred and no warning issued by traffic control.
