Narrative:
We had been cleared to descend to cross rhyme intersection at 10000'. Out of 17000', I called for the descent checklist. We now do a checklist by memory first, then check it. I looked in the darkened cockpit at the ATIS card and the captain pointed at it and said, 'conditions have improved significantly since we left, haven't they?' I noted the altimeter setting as 2963 and set this. We completed the descent check, setting bugs, etc. I was about to brief the approach when center called and said we were showing 300' low. It was at this point he gave us the altimeter setting as 29.38. I know he had not give this to us earlier as I would have noted the difference. The captain had made the mistake and was looking at the departure side of our ATIS card when he called 29.63 on the altimeter. Contributing factors were being tired and the darkened cockpit.

Title: ACR MLG ALT DEVIATION OVERSHOT. ALTIMETER SET WRONG BECAUSE THE PIC HAD USED THE DEP SIDE OF THE ATIS CARD INSTEAD OF THE ARR SIDE.
Narrative: WE HAD BEEN CLRED TO DSND TO CROSS RHYME INTXN AT 10000'. OUT OF 17000', I CALLED FOR THE DSCNT CHKLIST. WE NOW DO A CHKLIST BY MEMORY FIRST, THEN CHK IT. I LOOKED IN THE DARKENED COCKPIT AT THE ATIS CARD AND THE CAPT POINTED AT IT AND SAID, 'CONDITIONS HAVE IMPROVED SIGNIFICANTLY SINCE WE LEFT, HAVEN'T THEY?' I NOTED THE ALTIMETER SETTING AS 2963 AND SET THIS. WE COMPLETED THE DSCNT CHK, SETTING BUGS, ETC. I WAS ABOUT TO BRIEF THE APCH WHEN CENTER CALLED AND SAID WE WERE SHOWING 300' LOW. IT WAS AT THIS POINT HE GAVE US THE ALTIMETER SETTING AS 29.38. I KNOW HE HAD NOT GIVE THIS TO US EARLIER AS I WOULD HAVE NOTED THE DIFFERENCE. THE CAPT HAD MADE THE MISTAKE AND WAS LOOKING AT THE DEP SIDE OF OUR ATIS CARD WHEN HE CALLED 29.63 ON THE ALTIMETER. CONTRIBUTING FACTORS WERE BEING TIRED AND THE DARKENED COCKPIT.
