EVA air and Bangkok

I must have flown with EVA air about 14 times over the past year between Bangkok and Taipei and every single time the posted boarding time has been wrong. I know they have a schedule which they must post but what is the point of posting a schedule if you never keep it? The result is usually anxious agitated customers who at the first sign of any activity race to form and/or butt into the que. This being the information age is it not too much to expect real time delivery of this type of data? Would this not be an acceptable solution?
Of course this in no way compares to any of my experiences or others with the “new aeroflot” Air Canada. Delays, poor customer service, and lack of information are a hallmark of their brand.
