When using logback's DBApprender, script for creating tables have to be run.

Oracle handles timestamps in other way, than other databases, in can have only 9 digits there. In recent script Timestamp is stored as Number and is completely useless, because number "1395673233762" really does not say anything.

In attachment there is script, what adds other column to LOGGING_PROPERTY, where is normal timestamp recounted from this magic number. Now logging events to Oracle works like a charm
