What is Unix Timestamp?
A Unix timestamp (also known as epoch time) is the number of seconds or milliseconds that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch). It's a widely-used method for tracking time in computer systems because it's timezone-independent and easy to calculate with.
Common Use Cases
- Debugging API responses with timestamp fields
- Converting database timestamps to readable dates
- Analyzing server logs and system events
- Working with scheduling systems and cron jobs
- Testing date-based features in applications
- Converting between different timezone representations
Seconds vs Milliseconds
Unix timestamps can be expressed in seconds (10 digits, e.g., 1609459200) or milliseconds (13 digits, e.g., 1609459200000). Our converter automatically detects which format you're using. JavaScript and many modern APIs use milliseconds, while traditional Unix systems use seconds.
Privacy & Security
All timestamp conversions happen locally in your browser using JavaScript. No data is sent to any server, ensuring complete privacy and security for your timestamps and dates.
