dateutil seems to give wrong timezone

Question

I use datetime and dateutil to get my current UTC offset and time zone like this:

>>> from datetime import datetime
>>> from dateutil.tz import tzlocal
>>>
>>> current_time = datetime.now(tzlocal())
>>> print('Your UTC offset is {:+g}'.format(current_time.utcoffset().total_seconds()/3600))
Your UTC offset is +2
>>> print('Your time zone is {}'.format(current_time.tzname()))
Your time zone is W. Europe Daylight Time

The UTC offset is correct, but not the time zone. I have Central European Daylight Time; besides, Western European Daylight Time is UTC+1 so it doesn't even match with the UTC offset that is printed. So why does this code print "W. Europe Daylight Time" and not "C. Europe Daylight Time"?
