Yes, I have the same issue as well.

HI @schrein, Can you test with this #16 PR which fix Pcap timestamp and if you confirm me that it's ok I will publish an aggregation_tools bugfix release code with it.

fkerem commented 3 years ago

When I try to run it with Python2, it says ImportError: No module named iotlabcli. I can confirm that the issue has resolved when Python3 is used @fsaintma, thanks! There are no any negative timestamps now.

fkerem commented 3 years ago

Today, I was experimenting with 1 BR and 1 hello-world example node and saw that there is one negative timestamp in the pcap. I was using fix-timestamp branch of your PR @fsaintma :/

I think for the early messages it’s normal because of relative time stamp of both remote sniffer .
