FAQ
What’s the difference between seconds and milliseconds timestamps? Seconds: Used by Unix/Linux systems (10 digits). Milliseconds: Used by JavaScript and some APIs (13 digits, 1000x larger).
Why does my timestamp have more digits? 10 digits = seconds, 13 digits = milliseconds. Add three zeros to seconds to get milliseconds.
What happens in 2038? The Year 2038 problem affects 32-bit systems when timestamps exceed 2,147,483,647. Modern 64-bit systems aren’t affected.
