Narrative:
Both crew members forgot to reset their altimeters to 29.92 passing FL180 on climb out. We leveled at FL260, but due to turbulence requested a descent to FL220. We descended to FL220. While level at FL220, center questioned our altitude, and we then noticed we still had 30.25 in the windows. We reset the altimeters and the aircraft corrected to the correct FL220. Factors that contributed to my missing this. 1) flying on the back side of the clock (night) after trying to sleep in a hotel. 2) having done very little flying in the past 60 days, I felt rusty. 3) being distraction by the turbulence, and 4) distraction by other cockpit duties and not adequately backing up the PF (the first officer) and missing the altimeter setting change on climb out.

Title: AFTER BEING QUESTIONED ABOUT THEIR ALT, AN ACR CREW DISCOVERS THEY HAVE NOT RESET THEIR ALTIMETERS TO QNE AS REQUIRED BY FAR SECTION 91 PT 121.
Narrative: BOTH CREW MEMBERS FORGOT TO RESET THEIR ALTIMETERS TO 29.92 PASSING FL180 ON CLBOUT. WE LEVELED AT FL260, BUT DUE TO TURB REQUESTED A DSCNT TO FL220. WE DSNDED TO FL220. WHILE LEVEL AT FL220, CTR QUESTIONED OUR ALT, AND WE THEN NOTICED WE STILL HAD 30.25 IN THE WINDOWS. WE RESET THE ALTIMETERS AND THE ACFT CORRECTED TO THE CORRECT FL220. FACTORS THAT CONTRIBUTED TO MY MISSING THIS. 1) FLYING ON THE BACK SIDE OF THE CLOCK (NIGHT) AFTER TRYING TO SLEEP IN A HOTEL. 2) HAVING DONE VERY LITTLE FLYING IN THE PAST 60 DAYS, I FELT RUSTY. 3) BEING DISTR BY THE TURB, AND 4) DISTR BY OTHER COCKPIT DUTIES AND NOT ADEQUATELY BACKING UP THE PF (THE FO) AND MISSING THE ALTIMETER SETTING CHANGE ON CLBOUT.
