How it works
- Batch paste with per-line unit auto-detection for seconds, millis, micros and nanos
- Output in ISO, local, UTC and relative form
- Annotate mode finds timestamps inside pasted log lines and appends human dates
- Reverse mode converts dates back to epoch in your chosen unit
- Copy-ready CSV export with raw, iso, local and relative columns
