Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent time in computer systems and is timezone-independent.
What's the difference between seconds and milliseconds?
Unix timestamps can be in seconds (10 digits, like 1640995200) or milliseconds (13 digits, like 1640995200000). JavaScript uses milliseconds internally, while many other systems use seconds.
How are timezones handled?
Unix timestamps are always in UTC. When converting to human-readable dates, you can specify the timezone for display purposes. The tool uses your browser's timezone information for accurate conversions.
Is my data secure when using this converter?
Yes, absolutely. All conversions happen entirely in your browser using JavaScript. No timestamps or dates are sent to any server, ensuring complete privacy and security.
What is relative time?
Relative time shows how long ago or in the future a timestamp is from the current time (e.g., "2 hours ago", "in 3 days"). This is useful for understanding timestamps in a more human context.
