Timestamp Converter
Convert between Unix timestamps and human-readable dates.
About Timestamp Converter
Timestamp Converter converts between Unix timestamps and human readable dates in both directions, showing local time, UTC and ISO 8601 format side by side for the same moment.
Reach for this when debugging a log file or API response that only shows a raw timestamp, when working out how a specific moment looks in a different timezone, or when checking a value close to the 32 bit rollover in 2038 out of curiosity.
It accepts both ten digit seconds values and thirteen digit milliseconds values and works out automatically which one it has been given, so there is no need to know in advance which format a particular system used.
