## Discrepancy

ON DESCENT, A BURNED ELECTRICAL ODOR ASSOCIATED WITH AN IDS DU STATUS MESSAGE WAS NOTICED ON THE FLIGHT DECK.  UNABLE TO BRING UP LOWER EICAS DURING THAT TIME, ODOR CEASED WHEN MESSAGE EXTINGUISHED.  FOUND CAPTAIN'S DIGITAL CLOCK INOPERATIVE.  THE E7/CHR LETTERS BURNED OUT. THE CLOCK WAS REPLACED IAW AMM 31-25-01/401. OPS WAS NORMAL IAW AMM 31-25-00/501.  NO FURTHER ODOR WAS NOTICED.
