About the Timestamp Converter
A Unix timestamp counts the seconds (or milliseconds) since 1 January 1970 UTC. It is the standard way systems store and exchange points in time, but it is unreadable to humans. This converter translates in both directions: paste an epoch value to see the corresponding date in UTC, local time and ISO 8601, or pick a date to get its timestamp.
It automatically detects whether your input is in seconds or milliseconds and updates live. Everything runs locally, so there is no network round-trip — handy when debugging log timestamps, token expiries or scheduled jobs.
How to use the Timestamp Converter
- 1Enter a Unix timestamp to convert it to a date, or pick a date to get its timestamp.
