Current Unix time
What is Unix time?
Unix time counts seconds since 00:00:00 UTC on 1 January 1970. JavaScript commonly uses milliseconds, so this tool detects both formats by magnitude.
FAQ
Are local and UTC times different values?
No. They are two representations of the same instant.
What is the 2038 problem?
Some signed 32-bit systems overflow their seconds counter in January 2038; modern browser dates are not limited that way.
