Paste messy log output and every timestamp hiding in it — Unix seconds, milliseconds, or ISO 8601 — gets found and converted automatically.
The scanner checks every line for two patterns: a bare Unix timestamp (a 10-digit number for seconds, or 13 digits for milliseconds, the kind you'd see in ts=1752762721 or a raw JSON field) and an ISO 8601-style date-time string (2026-07-17T14:32:01Z or 2026-07-17 14:32:01). It's built for messy, real log output — pasting a whole line of noise works the same as pasting a bare number.
For a clean list of timestamps with nothing else around them, the Batch Converter is faster. This tool exists specifically for when the timestamps are buried in something else.
