Narrative:
I was the pilot in command (PIC) non flying pilot. We were on the descent into midway airport. We were cleared from the fl's to 4;00 MSL with an altimeter setting of 30.36. Reaching 4;000 we were questioned about our altitude; something about check your mode C and altitude. I stated we were level at 4;000 MSL; ATC stated they showed us at 3;000. I asked her to confirm the altimeter setting and was given a new setting of 29.44. At this point I'd guess we were 40 miles from the airport.obviously we flew through a weather front and I should have picked up on the setting that we were given was significantly different from the destination.
