custom logger in V3 SDK does not get the time it took for the request to complete.

Hi
we are migrating from v2 to v3.
we have a custom logger that we pass the sdk.
In v2 the logs we got where build by your V2 SDK , and contained among other things the time it took for the request to finish.
Below is an example of log by V2 sdk - see the 0.528 seconds .
[AWS ec2 400 0.528s 0 retries] deleteSecurityGroup({ GroupId: 'sg-079bfdf0d369d0efe' })
In V3 , our logger in called with an object containing clientName, commandName, input , output and metadata. There is no information regarding the time the request took.
This information is critical for us and without this , we will have problems migrating.
Is there anything that can be done to get the request duration.
Thanks.
