The SEP Small Business Edition website (hostedendpoint.spn.com), and the reports generated by the website, have no facility to generate Date/Time fields in any other format than the default American M/D/Y which is not suitable for many people and can cause confusion when recipients of the reports in the UK/Europe are not aware they're generated by a USA-configured report generator.
At least 2 settings would be required
1) Enable user to choose preferred date format (i.e. DD/MM/YYY, M/D/YY etc etc)
2) Time format in 12/24 hour format
These settings should be applied at the User Profile in order to display date/times on the website in the preferred format, and in the Report Settings to generate reports with datetimes in preferred format.
