Unix Timestamp Converter

Convert between local time and Unix timestamps (seconds/milliseconds) with full timezone support. Features real-time current timestamp display and one-click copy.

All tools on this site run entirely in your browser locally. No data is uploaded to any server.

Features:

• Shows your browser's local IANA timezone name, standard/DST status, and current offset; timezones can be freely switched
• Live display of the current local time along with corresponding 10-digit (seconds) and 13-digit (milliseconds) timestamps
• Convert timestamps to local time with automatic 10/13-digit detection: 10-digit values are treated as seconds, 13-digit as milliseconds
• Convert local time to timestamp in either seconds (10-digit) or milliseconds (13-digit)
• 1 second = 1,000 milliseconds; simply append three zeros to a 10-digit timestamp to convert it to 13-digit format
• Built-in date picker with one-click current time insertion
• One-click copy for conversion results

Common uses:

• Converting between database timestamps and readable date/time values
• Timestamp conversion and validation while debugging APIs
• Reading and interpreting timestamps in log files
• Standardizing timestamp formats across different programming languages
