Narrative:
Crossed spane intersection at FL190, speed 280 KTS. Approach gave us a descent to 15000 ft and cleared direct dryuc. Started descent to 15000 ft and was looking for dryuc on FMS. It was not on our route and between looking for dryuc and querying ATC, aircraft leveled at 15000 ft with altimeter set at 29.92. The current altimeter was 29.45. Approach recleared aircraft to chipp intersection and controller queried our altitude.

Title: B767 DISTR FLC DEPENDS ON AUTOPLT TO LEVEL OFF AT CORRECT ALT AND NEGLECTS TO RESET CURRENT LCL ALTIMETER.
Narrative: CROSSED SPANE INTXN AT FL190, SPD 280 KTS. APCH GAVE US A DSCNT TO 15000 FT AND CLRED DIRECT DRYUC. STARTED DSCNT TO 15000 FT AND WAS LOOKING FOR DRYUC ON FMS. IT WAS NOT ON OUR RTE AND BTWN LOOKING FOR DRYUC AND QUERYING ATC, ACFT LEVELED AT 15000 FT WITH ALTIMETER SET AT 29.92. THE CURRENT ALTIMETER WAS 29.45. APCH RECLEARED ACFT TO CHIPP INTXN AND CTLR QUERIED OUR ALT.
