Frequently Asked Questions
What is a Unix timestamp?▼
A Unix timestamp is the number of seconds since January 1, 1970 00:00:00 UTC (the Unix Epoch). It is timezone-independent and universally supported.
Why do some timestamps have 13 digits?▼
13-digit timestamps are in milliseconds (not seconds). Divide by 1000 to convert to seconds. JavaScript's Date.now() returns milliseconds.
What is the maximum Unix timestamp?▼
For 32-bit systems: 2,147,483,647 (January 19, 2038). For 64-bit systems the limit extends billions of years into the future.
