In regards to being on time to chat here is a way to be able to change the calendar to show your time zone. This is the easiest way I have found.

Put your curser on the tab that says My Profile
Click on the area of Edit Personal
On the left side of this page there is a section for Your Control Panel
Scroll down to where it says Settings & Options
Click on the option of Edit Options
Scroll down to Date and Time Options
Set the first area to your time zone and scroll down and click Save Changes

This should set the calendar to your time zone so you know when chats start for you.

I hope this helps
