❓ Frequently Asked Questions
Everything you need to know about Unix timestamps
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 (the Unix epoch). It's a standard way to represent time in computer systems and is widely used in programming and databases.
What's the difference between seconds and milliseconds?
Seconds: Standard Unix timestamp (10 digits for current dates)
Milliseconds: Unix timestamp with millisecond precision (13 digits for current dates)
Our tool automatically detects which format you're using based on the number of digits.
How do I know if my timestamp is in seconds or milliseconds?
Generally, timestamps with 10 digits are in seconds, while those with 13 digits are in milliseconds. For example: 1699363200 (seconds) vs 1699363200000 (milliseconds). Our tool automatically detects the format and shows you which one it detected.
Why do I need to consider time zones?
Unix timestamps are always in UTC, but when converting to human-readable dates, you need to specify the time zone for accurate local time display. This is crucial for applications that serve users in different geographical locations.
Is my data secure when using this tool?
Yes! All conversions happen directly in your browser using JavaScript. No timestamps or dates are sent to our servers or stored anywhere. The tool works completely offline once the page is loaded.
