Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC). It's a standard way to represent dates and times in computer systems and is timezone-independent.
What's the difference between 10-digit and 13-digit timestamps?
10-digit timestamps represent seconds since the Unix epoch, while 13-digit timestamps represent milliseconds. This tool automatically detects which format you're using.
Why use Unix timestamps?
Unix timestamps are timezone-independent, easy to compare and sort, and take up less storage space than formatted date strings. They're widely used in databases, APIs, and programming.
What is ISO 8601 format?
ISO 8601 is an international standard for date and time representation (e.g., 2024-12-18T10:30:00.000Z). It's unambiguous, sortable, and widely supported across programming languages.
Are Unix timestamps affected by timezones?
No, Unix timestamps always represent UTC time. When converting to a human-readable format, you can then apply timezone conversions as needed.
