2nd-order-accuracy in time for Projection method

I am working to increase the degree of accuracy of a 3D flow model which is based on projection method. It is a 2nd-order accurate scheme in space and time, but pressure ends up in 1st-order accuracy (in time) no matter what the accuracy of the whole scheme is. I would like to discuss the issues for the 2nd-order-accuacy and especially the concerns which may rise over the boundary conditions. Any comments on this is most appreciated. Cheers

Please check out the following reference:

The paper of Gresho, P.M is also very useful.
