Convert timestamps without leaving your browser
Use this timestamp converter to switch between Unix seconds, epoch milliseconds, UTC dates, and local date-time values. It is useful for debugging logs, API payloads, database records, and scheduled jobs when you need a quick readable time check.
Unix seconds vs milliseconds
Many APIs store epoch time in seconds, while JavaScript dates and event logs often use milliseconds. The converter keeps both outputs visible so you can spot unit mismatches before they become off-by-1000 bugs.
