Narrative:

This flight operated from lax to hnl via R576. I was flying and the captain was doing the radio work and making the position reports. During the preflight checks all 3 crew members failed to notice that all 3 clocks were set 12 mins slow. Consequently, every position report from duets to duffe was estimated and reported 12 mins late. We did not realize the clocks were off until the second officer and a dead-head were discussing what time we were going to arrive and they noticed a discrepancy between their watches and the aircraft clocks. This occurred between duffe and denns intersection and we promptly informed ATC. The aircraft had just come out of a phase check and we theorize that they must have disconnected the batter causing the clocks to stop. The cause of this incident was a lax preflight procedure. The aircraft was late and they were pressuring us to get it out of there, although I realize this is no excuse.

Title: OCEANIC CARGO FLT HAS MIS-SET CLOCKS. POSITION REPORTS NOT ACCURATE.

Narrative: THIS FLT OPERATED FROM LAX TO HNL VIA R576. I WAS FLYING AND THE CAPT WAS DOING THE RADIO WORK AND MAKING THE POS RPTS. DURING THE PREFLT CHKS ALL 3 CREW MEMBERS FAILED TO NOTICE THAT ALL 3 CLOCKS WERE SET 12 MINS SLOW. CONSEQUENTLY, EVERY POS RPT FROM DUETS TO DUFFE WAS ESTIMATED AND RPTED 12 MINS LATE. WE DID NOT REALIZE THE CLOCKS WERE OFF UNTIL THE S/O AND A DEAD-HEAD WERE DISCUSSING WHAT TIME WE WERE GOING TO ARRIVE AND THEY NOTICED A DISCREPANCY BTWN THEIR WATCHES AND THE ACFT CLOCKS. THIS OCCURRED BTWN DUFFE AND DENNS INTXN AND WE PROMPTLY INFORMED ATC. THE ACFT HAD JUST COME OUT OF A PHASE CHK AND WE THEORIZE THAT THEY MUST HAVE DISCONNECTED THE BATTER CAUSING THE CLOCKS TO STOP. THE CAUSE OF THIS INCIDENT WAS A LAX PREFLT PROC. THE ACFT WAS LATE AND THEY WERE PRESSURING US TO GET IT OUT OF THERE, ALTHOUGH I REALIZE THIS IS NO EXCUSE.
