------------------------------------------------
Resolution: Fixed
> Expose log record append time to the controller/broker
> ------------------------------------------------------
>
> Key: KAFKA-12997
> URL: https://issues.apache.org/jira/browse/KAFKA-12997
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Niket Goel
> Assignee: Jose Armando Garcia Sancio
> Priority: Minor
> Labels: kip-500
>
> The snapshot records are generated by each individual quorum participant
> which also stamps the append time in the records. These appends times are
> generated from a different clock (except in the case of the quorum leader) as
> compared to the metadata log records (where timestamps are stamped by the
> leader).
> To enable having a single clock to compare timestamps,
> https://issues.apache.org/jira/browse/KAFKA-12952 adds a timestamp field to
> the snapshot header which should contain the append time of the highest
> record contained in the snapshot (which will be in leader time).
> This JIRA tracks exposing and wiring the batch timestamp such that it can be
> provided to the SnapshotWriter at the time of snapshot creation.
