function test_timespan(varargin)
% A test function to submit a timespan to the repository. The timespan is then
% retrieved and compared to the original one.

% Usage: test_timespan()     - connects to Hannover repository
%        test_timespan(conn) - connects to the repository specified by
%                                  the database conn object.
