+Patchable constant used in the shutdown server. 
+Used to calculate the shutdown timer with KShtdwnTimeoutClient.
+It represents the base timeout value in microseconds.
+
+The timeout is calculated as:
+KShtdwnTimeoutBase + KShtdwnTimeoutClient * numClients,
+where numClients is the number of connecting clients.
+
+If the timeout value is;
+-1, the timer is not used, the server will wait for all client's registration 
+    before executing the shutdown;
+0,  the timer expires immediately, the server will execute the shutdown immediately, 
+    not waiting for any client's re-registration.
+other value greater than 0, the server will wait a certain period of time for the clients' registration 
+    and execute the shutdown if the timer expires or all clients re-register.
+    
+Licensees who wish to alter these patchable constants will need to define 
+these ROM build-time macros in their product HRH or IBY files.
+
+The new values must follow the rule:
+KShtdwnTimeoutBase >= -1 and
+KShtdwnTimeoutClient >= 0.
+
+Otherwise, the server panics with KErrNotSupported.
