Frequently Asked Questions
Which timezone is shown?
UTC is used for the output.
Does it use an API?
No.
Seconds or milliseconds?
Unix time counts seconds since 1 January 1970 UTC. Many JavaScript systems use milliseconds, which gives a number with 13 digits instead of 10. The tool detects the length and converts accordingly.
Results are shown in UTC. If a time looks hours off, the cause is usually a time zone difference between the system that produced the value and your local clock.
