Narrative:
Over makam intersection the first officer gave a position report and an estimate to awk. I did not look at his work at this time. We crossed awk. He was busy so I picked up the paperwork to give the position report. I then noticed the discrepancy. I asked him about it, it was discovered that after crossing makam intersection he gave the estimate to selly intersection 23 mins instead of the 47 mins to awk. Center was called and apologies made. Supplemental information from acn 187330: we had flown from honolulu to narita, then had a 12 hour layover. Then we flew 3 1/2 hour to saipan for honolulu factoring in 6 time zones crossed makes this an unusually tiring trip.
