The Sybase package contains an extension module written in C. The extension module is used by the Python wrapper module Sybase.py.
The Sybase package uses the Sybase client libraries which should have come as part of your Sybase installation.
If you are using Linux, Sybase provide a free version of their database which can be downloaded from http://linux.sybase.com/.
If the mxDateTime package is installed the Sybase
module can return
datetime values as DateTime objects.

DateTime object defined in the sybasect extension
