About This Tool

Convert Unix timestamps and human-readable dates so developers can inspect logs, APIs, database values and event times more easily.

How to Use It

Enter the timestamp or date value, select the required conversion and review the corresponding representation. Confirm whether the source value is seconds or milliseconds when working with application data.

How It Works

Unix time represents elapsed time from the Unix epoch, normally using seconds or milliseconds depending on the system. Time-zone display affects human-readable output but not the underlying instant.

Practical Example

A Unix timestamp from an API may be in milliseconds while another system expects seconds. Identifying the unit before conversion prevents a result that is off by a factor of 1,000.
