How this module print the time zone?

First of all, thank you for your work with this module.

Problem/Motivation

I try to print the date field time zone in to the twig file. I thought If I use this module it print the time zone in the time field, unfortunately I don't see the right time zone here

<time datetime="2022-09-29T10:00:00Z">September 29, 2022 10:00 AM</time>

I would like to see this:
<time datetime="2022-09-29T10:00:00-03:00"> September 29, 2022 10:00 AM</time>

Of course maybe I misunderstood something, please help clear this up.
