In fact, it should be written as:
    return int(tz[0:3])*3600+int(tz[0]+tz[3:5])*60
to correctly handle minute part.

_tzoffset() returns negative offset for timezone names written like '+0200' because the first character is not being taken into account.

Example:
>>> from DateTime.DateTime import _tzoffset
>>> _tzoffset('GMT+0200', time())
7200
>>> _tzoffset('+0200', time())
-7200

Proposed solution:
in _tzoffset definition (DateTime.py) the line
    return -int(tz[1:3])*3600-int(tz[3:5])*60
should be changed to
    return int(tz[0:3])*3600-int(tz[3:5])*60
