Frequently asked questions
What is a Unix timestamp?
The number of seconds elapsed since 1 January 1970 00:00:00 UTC (the "epoch"). It is the standard machine-readable time format used in databases, APIs and logs.
Seconds or milliseconds — how do I tell?
Second timestamps are currently 10 digits (e.g. 1765286400); milliseconds are 13 digits. This tool detects the length automatically and labels which it assumed.
What timezone are results shown in?
Local time uses your device timezone; UTC and ISO 8601 are also shown so you can use whichever your system needs.
What happens in 2038?
Systems storing timestamps as signed 32-bit integers overflow on 19 January 2038. Modern 64-bit systems and JavaScript are unaffected.
