I think it is more important to keep the common time zone we currently have in the middle of the EU than where exactly it is. So it makes sense to delay a decision, until an agreement across the member states of that time zone can be reached. And as most of the time zone already is in the "plus" vs. the astronomical time, standard time would be the very obvious choice.
