formatISO does not support milliseconds

[fregante]

I'm looking to use formatISO to preserve the time zone, but it does not match the ISO used by JavaScript itself and there doesn't seem to be an option to enable it:

const date = new Date();

console.log(date.toISOString())
// "2022-02-20T04:00:45.418Z"

console.log(_.formatISO(date))
// "2022-02-20T12:00:45+08:00" <-- missing 418 milliseconds

I think this is same as #2965

This is not a documentation issue. That issue does not mention milliseconds at all

[mandaputtra]

Yes from the title, but this sentence are basically the same.

Executing that very code in the console comes back with '19:00:52-07:00' and not '19:00:52Z'.

I'm still looking up into this problem

Can you reopen this issue while you investigate? Regardless of what it "looks like" this is a feature request / inconsistency report. The only thing in common with #2965 is the affected function.

Terima kasih mas 🙏

I'm wrong, after looking up, turns out milliseconds aren't implemented yet. Sorry. Please review my draft if it is okay or not.
