Narrative:
ATC advised that we showed an altitude readout of FL354. We were tired after a long duty day and distraction at FL180. Where we normally set our altimeters to 29.92 (was set at 29.54) the departure airport setting, we reset 29.92 and descended to FL350 uneventfully. The distrs were with ATC changing heading, airspeed, and altitudes in clrncs.
