The library reports what it received from the server.  The server
converted the SQL DATETIME2(3) datatype of the column to varchar
for compatibility with the TDS version you're using.  

If you check with TDSDUMP, I believe you'll find you're connecting with
TDS 7.2.  The first version of the protocol to support DATETIME2 is
TDS 7.3.  The current release, 0.91, doesn't support TDS 7.3; to get
that, you'll need to use a recent snapshot.   

(The snapshots are once again broken.  I haven't had a chance to figure
out why.  To get the absolute latest, you need git.)  

Hoppas det blir klart.
