I have log files with an almost RFC3339Nano formatted timestamp. But only almost.
When trying to set the log entry pipeline as part of a pipeline, promtail complains about “extracted data did not contain a timestamp”.
A log line can look like this:
227320 20200519T232044.113+0200 WARN hostname1 System.Scheduler.
What are my options for using that timestamp in the pipeline, getting correct log entry timestamps in Loki (and Grafana) down the road?
