One more "'tzoffset' object has no attribute 'zone' " #1928
Description
Version: 0.9.0.dev_de31cbe (py2.7-macosx-10.6-x86_64)
Related to #1922 (closed)
I could be the only dummy with this kind of data so I might be able to find a few more of these.
Although I think these are typical Postgres tz-aware timestamps.
