Timestamp precision of the consolidated database is higher than attainable by the remote database. If possible you may lower the timestamp precision on the consolidated database to avoid inconsistent timestamp data between the remote and the consolidated database. Otherwise, you may need to avoid synchronizing timestamps in your synchronization schema; or you may need to have conflict detection scripts aware of the virtual difference; or you may need to use the -zp command line option to tolerate the conflict. Your application should also be able to deal with the inconsistency.
