The date picker control posts the date in display format back to the server. This causes issue with date parsing if the display format is not what is expected (i.e. configured) on the server.
I have attached an example project which reproduces the issue. The date format is set to dd/MM/yyyy. The example posts 8th December 2013 back to the server in in the display format as 08/12/2013 which is then misparsed as 12th August 2013 on the server.
