UTC converted to Central Europe Standard Time is 2 hours in front not 1

I'm trying to understand why my date is wrong:

DateTime databaseUtcTime = new DateTime(2016, 8, 15, 10, 20, 0, DateTimeKind.Utc);
var timeZone = TimeZoneInfo.FindSystemTimeZoneById("Central Europe Standard Time");
var testDateTime = TimeZoneInfo.ConvertTimeFromUtc(databaseUtcTime, timeZone);

testDateTime outputs 15/08/2016 12:20:00 rather than 15/08/2016 11:20:00 why is this? Shouldn't it be 1 hour forward from UTC, not 2 ?

EDIT----

Thanks Jon Skeet,

If this helps anyone, i resorted to using:

if(testDateTime.IsDaylightSavingTime())
{
    testDateTime = testDateTime.AddHours(-1);
}

Albeit you not knowing the context, this could be helpful to know how to get rid of daylight saving time when running certain explicit testing on time.
