Frequently Asked Questions
- What is a Unix timestamp?
- A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC. It is the standard way to represent points in time in programming.
- What timezone is used?
- The tool displays the converted date in your browser's local timezone by default, and also shows the equivalent UTC time for reference.
- What is the maximum timestamp value?
- The maximum 32-bit Unix timestamp is 2,147,483,647 (January 19, 2038). This tool uses JavaScript's 64-bit number representation, supporting dates far beyond 2038.
- What's the difference between seconds and milliseconds?
- Unix timestamps in seconds are the classic format used in most server languages. Milliseconds (×1000) are commonly used in JavaScript's Date.now(). The tool auto-detects which format you're using based on the number of digits.
