Hello Kristi,
Hope you're doing well.
In Reactive and Mobile Applications, when you are working on the Client-Side, it assumes the time of the client (and not of the Server). In this case, it is directly related to your browser.
I did publish your module and for me it appears my browser format and timezone:

Just try to change your time format in the browser and it should work as expected:

Hope that this helps you!
Kind regards,
