------------------------------------
Summary: Include timestamp in journal log entries
Key: OAK-4095
URL: https://issues.apache.org/jira/browse/OAK-4095
Project: Jackrabbit Oak
Issue Type: Improvement
Components: segmentmk
Reporter: Chetan Mehrotra
Priority: Minor
Fix For: 1.6
Currently the journal log has entries like below. At times while debugging
crash or some issue we need to determine the probable root state at some point
in the past.

Currently there is no way to determine from above log what is the root state
wrt time. So we need to workaround that by reading each root state and look for
some path which has some time related property. To simplify such case it would
be helpful to also include timestamp while adding a journal entry
