FAQ
What is a Unix timestamp?
A Unix timestamp (also known as POSIX time or Epoch time) is the number of seconds elapsed since January 1, 1970 at 00:00:00 UTC. It is a timezone-independent absolute time representation widely used in computer systems and network protocols.
What is the difference between second and millisecond timestamps?
Second-precision timestamps (10 digits) represent time to the nearest second, while millisecond-precision timestamps (13 digits) represent time to the nearest millisecond. Values greater than 10¹⁰ (10,000,000,000) are treated as milliseconds; smaller values are treated as seconds. This tool auto-detects the format.
