FAQ
What's the difference between seconds and milliseconds?
Unix timestamps are traditionally in seconds since 1 Jan 1970; many programming languages (like JavaScript) use milliseconds instead.
Why does my converted date look off by a few hours?
The date-to-timestamp conversion uses your browser's local timezone — check the UTC value for a timezone-independent result.
