[EWS JAVA API 1.1] Incorrect time from appointment object

When I add appointment for specific user on Exchnage Server, I do this through Outlook web app. Next I try to find appointments for specific user and time interval (CalendarView)

Calendar,calendarView);

exchange is ExchangeService object

Unfortunatly I always get Appointment.getStart.getTime 2 hours behind, compared to the time that I defined on appointment in outlook web app

example. getTime - 13:00h, Outlook web app - 15:00h
