+Returns the current time broken down. Note that this function returns a
+pointer to a static buffer that's reused by calls to this function and
+certain C library functions (e.g. localtime). If there is any chance your
+code might be used in a multi-threaded application, you really should use
+the flavour of function \helpref{wxDateTime::GetTmNow}{wxdatetimegettmnow}
