Major Description
OAK-3001 is about improving the JournalGarbageCollector by querying on a separated-out timestamp property (rather than the id that encapsulated the timestamp).
In order to remove OAK-3001 as a blocker ticket from the 1.2.3 release, this ticket is about adding a timestamp property to the journal entry but not making use of it yet. Later on, when OAK-3001 is tackled, this timestamp property already exists and migration is not an issue anymore (as 1.2.3 introduces the journal entry first time)
