Frequently Asked Questions
Everything you need to know about processing files securely in your browser
What date formats does this tool support?
This tool dynamically detects Unix epoch timestamps (seconds, milliseconds, microseconds, or nanoseconds), ISO 8601, RFC 3339, standard date strings (SQL formats like YYYY-MM-DD HH:mm:ss), time-only logs (HH:mm:ss.SSS), and Apache-style log dates (DD/Mon/YYYY:HH:mm:ss [+-]offset).
How does the Log Latency & Delta Analyzer work?
You paste a block of debug or server logs, and the tool extracts the timestamp from each consecutive line. It calculates the precise delay (delta) between them, allowing you to visually pinpoint performance bottlenecks and laggy steps instantly.
How are microseconds and nanoseconds handled?
When parsing epoch timestamps or date strings containing high-precision fractional seconds (e.g. .123456789), the tool extracts the extra precision using BigInt and accounts for it in both comparison and arithmetic modes.
Are my log files or timestamps sent to any server?
No. All text parsing, calculations, and rendering are executed client-side in your local browser sandbox. No data ever leaves your device, making it secure and fully offline-capable.
