Take the following timestamp: 1634587200000  
Convert it with:  
`unix2datetime(1634587200000) 53768-01-03T08:00:00`  
If I go to: [Unix Time Stamp - Epoch Converter](https://www.unixtimestamp.com/index.php), the result is `Mon Oct 18 2021 20:00:00 GMT+0000`

What am I missing?

From

```julia
?unix2datetime

```

you can see that the method expects seconds as an input. Your timestamp is in milliseconds.  
Try

```julia
unix2datetime(1634587200)

```

If you’re doing more work with unix timestamps, I made a package for this, [UnixTimes.jl](https://github.com/ancapdev/UnixTimes.jl). It uses a nanosecond representation and will let you preserve more accuracy than `DateTime` if you need it.

If you want others to use your package you’d be better off adding documentation 😉

Sure, generally do. This is a single type and a tiny amount of self explanatory code, which I’ve not been advertising, just seemed relevant and potentially useful in the context of this topic.
