yeldarb,
Registered Users set their own time zone in the User Control Panel.
Log into you account and click the "User CP" text link in the brown navigation bar that runs horizontally across top of the board pages.
In the page that will open up there is a "Control Panel" menu that runs vertically down the left side.
The first section of that menu is "Settings & Options". Click the "Edit Options" text link in that menu.
Scroll down to "Date & Time Options" until you see the drop down menu labeled "Time Zone". Open that menu and choose your local time zone.
A screenshot of the menu is attached
Let me know if there is anything else I can do to help.
