No, you got it wrong. The meridian of the CET is at the east German border. Only places east of it are in the "negative" time zone, less than one hour in difference. To the west, we have France already at +1, and Spain even at +2.
Permanent DST would put Poland at 0 to +1, Germany at +1 to +2, France at +2..+3.
