@BigOneLiu When the task info is created
https://github.com/apache/storm/blob/124acb92dff04a57b530ab4d95a698abc8ff46d9/storm-client/src/jvm/org/apache/storm/executor/Executor.java#L291-L293
The time that is set there is when the metric was sent (in seconds). In
most cases it should not take much if any time for it to make its way to the
metrics consumer, but if it does the times could be off from one another.
I personally am +1 for this change, because I don't really use this time
when I am looking at logged metrics, but if others want it they should speak up.
