Log Timestamp Normalizer
Paste logs with mixed timestamp formats and get them back in one format and one timezone. The tool detects each format it finds and explains anything it cannot parse.

Every line is scanned for the first recognizable timestamp. ISO 8601, slash dates,
Day Month Year, Month Day, Year, syslog dates without a year,
and 10- or 13-digit Unix epochs are supported. The matched text is replaced with the
chosen output format and timezone; the message around it is preserved. Timestamps that
carry an offset are converted from that offset, while timestamps without one are read in
the timezone you select. A year-less syslog date borrows the year found elsewhere in the
pasted text. Everything runs locally with the browser’s own Intl data.
