[jira] [Updated] (KAFKA-15068) Incorrect replication Latency may be calculated when the timestamp of the record is of type CREATE_TIME

     [ https://issues.apache.org/jira/browse/KAFKA-15068?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

hudeqi updated KAFKA-15068:
---------------------------
    Description: 
When MM2 is used to replicate topics between Kafka clusters, if the timestamp of the record of the source cluster is of type CREATE_TIME, then the value of timestamp may not be the actual "creation time (that is, append time)", for example, the value of timestamp is less than the current time for a long time (this is determined by the producer, and often occurs in the online environment), at this time, the calculated replication latency will be too large.

I understand that replication latency reflects the performance of replication and should not be affected by this abnormal situation.
