    Frequently asked questions

    What is a Unix timestamp?▾

    The number of seconds that have passed since 00:00:00 UTC on 1 January 1970 (the Unix epoch), not counting leap seconds. It is the same everywhere in the world, regardless of time zone.

    How do I know if a timestamp is in seconds or milliseconds?▾

    For current dates, a 10-digit number is seconds and a 13-digit number is milliseconds (JavaScript's Date.now()). 16 digits is microseconds and 19 is nanoseconds. Auto mode detects this for you.

    What is the Year 2038 problem?▾

    Systems that store Unix time as a signed 32-bit integer overflow at 2,147,483,647 seconds — 03:14:07 UTC on 19 January 2038. Modern 64-bit systems are not affected.

    How do I get the current timestamp in code?▾

    JavaScript: Math.floor(Date.now() / 1000). Python: int(time.time()). PHP: time(). SQL (PostgreSQL): extract(epoch from now()).
