>             Project: Bookkeeper
>          Issue Type: New Feature
>          Components: bookkeeper-client, bookkeeper-server
>    Affects Versions: 4.3.1
>            Reporter: Enrico Olivelli
>             Fix For: 4.4.0
>
>
> I think that a creation timestamp would be very useful and it does not cost 
> very much. It would be an immutable value. 
> Nowadays (on 4.3.1) I must keep that info together with the id of the ledger, 
>  for instance in zookeeper,  but if that reference gets lost there is now way 
> to know how old a ledger is.
> I think that this timestamp should be captured on client while calling 
> createLedger or asyncCreateLedger.
> In addition to this very common field maybe it would be useful to add a 
> custom byte[] field named "custom client data" in order to let the client 
> 'describe' the ledger without the need of extra data on Zookeeper.
