Narrative:

Departed teb using the TEB5 departure into low ceiling and IMC conditions. Procedure calls for a turn at 1500 ft to and climb to 2000 ft direct to pnj. Upon switching frequency from tower to ATC we were instructed to climb to 6000 ft and assigned a different heading than the TEB5 departure calls for. Shortly thereafter we were instructed to stop climb and maintain 3000 ft. ATC questioned our altitude and advised us to be sure our pitot heat was on. We scanned our instruments and discovered our altimeters were set to the setting from the previous day. We corrected the setting and continued the flight without further issues. ATC position checked our altitude for a while until they were confident of our altitude readouts. In future a lesson on not being rushed and completing checklists without distraction would have prevented this event.

Title: FAILURE BY C560 FLT CREW TO SET ALTIMETERS TO CURRENT PRESSURE RESULTS IN ALT DEV ON TEB SID FROM TEB.

Narrative: DEPARTED TEB USING THE TEB5 DEP INTO LOW CEILING AND IMC CONDITIONS. PROC CALLS FOR A TURN AT 1500 FT TO AND CLB TO 2000 FT DIRECT TO PNJ. UPON SWITCHING FREQ FROM TWR TO ATC WE WERE INSTRUCTED TO CLB TO 6000 FT AND ASSIGNED A DIFFERENT HDG THAN THE TEB5 DEP CALLS FOR. SHORTLY THEREAFTER WE WERE INSTRUCTED TO STOP CLB AND MAINTAIN 3000 FT. ATC QUESTIONED OUR ALT AND ADVISED US TO BE SURE OUR PITOT HEAT WAS ON. WE SCANNED OUR INSTRUMENTS AND DISCOVERED OUR ALTIMETERS WERE SET TO THE SETTING FROM THE PREVIOUS DAY. WE CORRECTED THE SETTING AND CONTINUED THE FLT WITHOUT FURTHER ISSUES. ATC POSITION CHKED OUR ALT FOR A WHILE UNTIL THEY WERE CONFIDENT OF OUR ALT READOUTS. IN FUTURE A LESSON ON NOT BEING RUSHED AND COMPLETING CHKLISTS WITHOUT DISTRACTION WOULD HAVE PREVENTED THIS EVENT.
