The short answer is I am not an expert on working with time zones within the Tableau product. But the good news is we have had other users with a similar scenario. I believe they were able to create the desired view though it takes some additional steps to implement. I am including a community post that discusses the possibilities for changing the timezone. As well as a third party blog that contains quite a bit of information on this ability.
Finally, I am including a Tableau Idea that can be voted on to show support for the feature of providing timezone conversion support, the idea can be found here: https://community.tableau.com/ideas/2607
I hope the helps!
