eDirectory issues a timestamp for every schema definition. These timestamp are issued starting at January, 1 1970 0:00. During installation, schema that is added first to a database is normally added with a timestamp that will close to January 1, 1970. This timestamp allows for the schema to be overwritten by the actual schema definitions in the tree the eDirectory Agent is being added to. This also allows for reduced complexity for the initial schema definitions during schema synchronization. It is normal for eDirectory operations if a schema definition has such a timestamp. If the definition is changed after installation, a timestamp closer to current time will be issued and synchronized throughout the tree.
All times in iMonitor are convert to the local time zone of the server iMonitor is running on before being displayed. This is why you might sometimes see time before 1970 due to the local time zone adjustment for display. If <No Date> is shown for a time value, the number of seconds since 1970 is 0.
