This removal won’t affect anything because it falls into the multi-format ? Both of those have timezone at the end so what happens if time stamp doesn’t have timezone, does it still match ?

Think I get it now. We need to do testing on k3s and rke logs to ensure this doesn’t regress.

Sorry for reply late, docker json-file logs and containerd logs format is different, but the time both field generate with RFC 3339Nano timestamp, related doc. Fluentd use strptime to parse time_format, strptime can handle the timezone.

Here is a similar PR in Kubernetes repo.

Need to backport to 2.4 also
