The Captain selected the new monthly database during our departure planning.  There was corrupted data for the ILS 30 OAK. We proceeded to the visual approach and landing rwy 30 OAK.
I loaded the new FMC Database a few hrs early during preflight. It was the effective date but it was not the time. This is not procedurally correct but I made an error regarding the time of changeover. However; by using this Database we discovered some discrepancies between it and the Jeppesen Database with the same effectivity that are significant. The OAK ILS 30 waypoints; MITOE and WUVON; had differing altitudes between Jepps and the FMS; plus the fix JENFR was missing. I got ahead of the timeline for updating the MD-11 FMS Database. I just looked at the effective date and updated without considering the Zulu Time. Discrepancies between the 2 Databases are outside my control. Wait until proper time to update FMS.
MD-11 flight crew changes the FMC database six hours early and finds that there are differences between the FMC OAK ILS 30 and the Jepp ILS 30 with the same effective date. A Visual Approach and landing is accomplished.
