@lrlna hi, I'd like to get this PR merged, in my case I wanted to use this tool to quickly review production logs without visually analysing/parsing all available data. It was a surprise to see all log entries to have the same timestamp when read from file (i.e.,jq -c 'select(.level >= 40)' app.log | pino-colada).

There's a bug currently which I described in a review. @rodrimc, I've left a suggestion with a fix you can apply in your PR. If you don't have any time right now I can create a new PR with a fix later this week.

Thanks!
