Unix Timestamp Converter

What is a Unix Timestamp?

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC) — the Unix epoch. It's used everywhere in programming:

• API responses and database records
• File modification times (touch, stat)
• Cookie and session expiration
• Log analysis and metrics

Tip: If a timestamp has 13 digits, it's in milliseconds (common in JavaScript's Date.now()). This tool handles both automatically.
