* The specified start and end time criteria are now properly used to limit the results.
* Two new elements, <certDate> and <installDate>, have been added to the <station> element in XML format. Note that these new elements are only included when they are defined in the virtual network definition, this is common for 'TA' network stations but very few others.
* The CSV format now includes the correct station installation and certification dates.
WARNING: in a future release the wayward <start> and <end> values for a <virtualNetwork> will be removed. They are left in for backwards compatibility but are not meaningful, as there is no start and end definition for a virtual network itself.
