Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds since January 1, 1970 (midnight UTC), used universally in computing.
How do I know if my timestamp is in seconds or milliseconds?
Our tool auto-detects the format. 10-digit numbers are typically seconds, 13-digit numbers are milliseconds.
Can I convert dates before 1970?
Yes! Negative timestamps represent dates before the Unix epoch. Our tool supports dates from ~1000 AD to ~3000 AD.
Is my data secure?
Yes, all conversions happen entirely in your browser. No data is sent to any server.
