Frequently Asked Questions
How does timestamp normalization work?
Each timestamp is detected by format (ISO 8601, epoch seconds/ms/us, CLF, RFC 2822, syslog) and converted to ISO 8601. Logs can be sorted and gaps detected.
What timestamp formats are supported?
ISO 8601, Unix epoch (seconds, milliseconds, microseconds), Apache CLF, RFC 2822, and syslog formats.
Do you upload my logs?
No. All normalization happens in your browser. Your timestamps and logs never leave your device.
Can I sort a log file by timestamp?
Yes. Paste log lines with timestamps and the tool sorts them chronologically.
What does find gaps do?
It detects gaps larger than one day between consecutive log entries, useful for finding missing data or outages.
Is there a file size limit?
No. The tool runs entirely in your browser with no uploads.
