Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 (UTC), also known as the Unix epoch. It is a universal way to represent a point in time independent of timezone.
Should I use seconds or milliseconds?
Unix timestamps are traditionally in seconds. JavaScript uses milliseconds (Date.now()). A 13-digit number is milliseconds; a 10-digit number is seconds.
Does this tool accept both seconds and milliseconds?
Yes. It auto-detects common Unix timestamp lengths and also accepts readable date strings for quick conversion.
