After import the ics file in Evolution application from out will get 3 hour difference from current calender
Example: We have a defibrillator training session at June 2 at 13.30−14.00 Helsinki time (+0300).
If you try to import ICS this into Evolution, the import dialogue will show the time apparently correctly as 13:30-14:00.
However, when it appears in the calendar, it's at 16:30 instead, which means the user who trusts this calendar import will miss it by 3 hours. I've seen events also be off by 1 hour when the invites are coming from
