## Description

I use this for Infoplus since I'm a remote worker and the warehouse is in a different time zone - the site uses my time zone to describe when an event took place, whereas I want the time zone the warehouse is in. I felt like this was missing from the available Add-Ons, as back when I used Chrome I was able to find one that did what I needed and apply it to that website only. So I used my programming knowledge and ChatGPT and built one for myself. Maybe other people will find it useful as well.
