@BryanBuckley ...
I know that there are time zone settings in both Canvas and within the Zoom integration with Canvas. For students, they can configure their time zone settings for the Canvas LMS by looking at this Guide:
For instructors, there are two areas where time zones can be set in the Canvas LMS:
This means that if your campus was located in the Central time zone, you could set it to that, and if you taught the course from your home on the East Coast, you could set your user account time zone setting to that time zone...and Canvas would figure all that out.
Now, for the time zone settings in the Zoom interface... I'm assuming that you are clicking on some sort of Zoom button on the left-hand side course navigation within your Canvas course. (Students would do the same thing.) When the Zoom interface appears, right underneath the Zoom logo it says, "Your current Tiem Zone and Language are {time zone, language}" with a pencil icon next to it. Both instructors and students would need to click on the icon to confirm that the time zone setting is correct on that screen, too. I used to be a Zoom admin at my previous employer, and I forget if there was a setting that carried over the time zone setting from Canvas to Zoom (or vice versa), but I think it's a good idea to double-check this setting just in case.
So, these are the areas you should check as an instructor, and your students should check their own time zone settings as well (you cannot control these for your students).
I hope this will be of some help to you.
