Hi, and welcome to the forums and station
.
As a test, I set my time preferences to GMT +2 and set "DST Correction Option" to "Automatically detect DST settings". What this got me was the forum reporting that the current time is GMT +3 (10:xx PM), which appears to be the correct summer time for your country.
If I look at the calendar now for a random event, say Gabriel Batz's
Montreal Mix Sessions, it shows 1:00 - 3:00 AM your time. Minus 3 hours from that to get to GMT would be 22:00 GMT. Minus another 4 hours to the current US Eastern time would be 18:00 Eastern, which is the correct time for his show.
So in short, as long as the bottom of the forum says the correct current time in your area, then the shows should be at the correct times for you as listed on the calendar.
What are your time options currently set at (User CP -> Edit Options)?
