Time Zone Summer Time Winter Time


I am in Romania , My timezone is GMT +2 , but now we are in winter time from the last sunday of november , our time zone is now GMT +3 , how can I implement the correct time in ewelink app, because I have scenes that open a gate at 7:00AM and close the gate at 18:00 PM , and now it opens at 6 AM and closes at 17:00 PM , where can we activate the daylight saving ?
(winter time – from last sunday octomber GMT +3
summer time – from last sunday march GMT +2 )
