Negative responsetime for HTTP call

Hi !
I have now played on packetbeat for a couple of weekds and everything was fine until I add new http ports on my packetbeat.yml configuration file. Since then, some events have been sent to the elasticsearch cluster with negative value for the responsetime field
.
Just to let you know, I am working with packetbeat and elasticsearch in docker containers. The WS is a spring boot application, deployed directly at the host level (no container).
The throughput is not so much : 1 call per second.

Thanks !

Damien

@bobmercer Which version of packetbeat are you using?
