Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is widely used in programming and databases to represent dates and times.
What is the difference between seconds and milliseconds timestamps?
Unix timestamps in seconds are 10 digits (e.g., 1700000000), while millisecond timestamps are 13 digits (e.g., 1700000000000). JavaScript Date.now() returns milliseconds, while most Unix systems use seconds.
Is this tool accurate for all timezones?
Yes, Unix timestamps are timezone-independent (always UTC). This tool correctly converts to and from your local timezone.
