zoom thinks my computer's timezone is CST

I've checked desktop and system settings, and also zoom time settings.  Zoom continues to give me reminders a whole hour before.  Somewhere Zoom thinks and reminds me of appointments a whole hour earlier than actual. 

How do I fix this.  I've done all the obvious fixes, need next level suggestions.
