Convert Unix epoch timestamps to UTC/local human-readable dates and vice versa.
A Unix Timestamp is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC (the Unix Epoch).
A timestamp converter translates Unix epoch timestamps (seconds or milliseconds since January 1, 1970) into human-readable UTC and local date-time strings, ISO 8601 format, and relative time expressions. OneToolBox's Timestamp Converter runs entirely in your browser — essential for developers debugging API responses, log files, and database records that store dates as Unix timestamps.
A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It's a standard way to represent dates and times in computing, used by most programming languages, databases, and APIs.
Yes. The converter automatically detects whether your input is in seconds (10 digits) or milliseconds (13 digits) and converts accordingly.
Yes. Enter a date and time in the date picker to get the corresponding Unix timestamp in both seconds and milliseconds format.
The converter displays both UTC (Coordinated Universal Time) and your local timezone simultaneously, so you can see both representations at a glance.
