The italki Calendar adjusts according to time zones, so there's often no need to change to your local time zone. But if you do want to change your local time zone, there are two ways:
The first way is to go to your italki Calendar and scroll to the bottom and click "Change my time zone".
The second way is to go to "Edit Profile" and adjust your "Local Time Zone" setting under the heading "Basic Information".
But what about Daylight Savings Time?
The italki Calendar is configured with Daylights Savings Time in mind. For example, if you scheduled a session this week (in "Fall Daylights Savings Time") for next week (which is in "Spring Daylights Savings Time"), you actually scheduled the session in the "Spring Daylights Savings Time". The calendar knows when "Daylights Savings Time" is for every country in the world, and all of the times are configured accordingly when you view the time table. Your schedule does not change, and your sessions will be at the time you schedule them for.
If you have read over the following information, your local time zone is set correctly and you still think there is an issue with your calendar, please email firstname.lastname@example.org to report the issue.
