Frequently asked questions
What is a Unix timestamp?
The number of seconds elapsed since 1 January 1970 00:00:00 UTC, ignoring leap seconds. It is the standard way computers store points in time.
How are milliseconds detected?
Values with 13 digits are treated as milliseconds, 16 digits as microseconds and 19 as nanoseconds. Ten-digit values are plain seconds.
What happens in 2038?
Systems that store the timestamp in a signed 32-bit integer overflow on 19 January 2038. Modern 64-bit systems are unaffected for billions of years.
Which date formats can I paste?
Anything the JavaScript Date parser understands: ISO 8601 like 2024-03-01T12:00:00Z, RFC 2822 strings and most common written dates.
