A practical Unix timestamp converter
Unix time counts seconds from 1970-01-01 UTC and is common in APIs, logs, databases, and developer tools. PicoBento recognizes ordinary seconds as well as larger millisecond values and shows the result in several useful formats.
Check time zones before you ship
The ISO result is unambiguous UTC, while the Local result uses the time zone configured in your browser. If a timestamp matters to a production system, compare the output with that system's documented time zone.
What is the difference between seconds and milliseconds?
Unix seconds are usually around ten digits. Unix milliseconds are usually around thirteen digits and represent the same instant with more precision.
