Hello Rex, how are you?

Look, you the only thing you should do is:

1. Click on your photo that is on the top on the right corner

2. Choose "edit" profile

3. Choose "time zone" 

and modify it. 

I hope this helps. However, if there's anything else you don't get, just go here: http://support.italki.com/hc/en-us

and you're going to find all answers that you need. 

Have a nice day. 

P.S. This is a discussion board about the Italian language.
