Wait. (that's My word lol) I can see why it's confusing. Something doesn't add up. I'm still trying to figure out why it's 7 pm MST when it's 9 pm EDT! There should be 3 hour's difference right now.

However, your chat is right behind DocJohn's, a one hour difference, right now. DocJohn's chat moves back (our time changes at 2 am, when it then becomes 1 am.) So to you in AZ, yes, it becomes one hour earlier.

You will need to move your chat.
