Italki automatically adjusts all schedules to your time zone. You can completely ignore the idea of time zones, as well as the idea of daylight saving time. It's all taken into account in the system! So if you want a session at 10am, book it at 10am. "4. Schedule a time: Then you will see the Teacher's Availability Schedule. You will see it according to YOUR time settings. Each member of italki sees their own schedule in their time zone. You do not need to know which timezone your teacher is in, italki figures this out for you!" http://support.italki.com/hc/en-us/articles/206352268-How-do-I-schedule-a-lesson-with-an-italki-teacher-
