 		 InvalidTime
 		 Failed }
 
+	A value of type RRCONFIGSTATUS returned when manipulating the output
+	configuration or querying information from the server that has some
+	time-dependency.
+	
+	InvalidConfigTime indicates that the supplied configuration
+	timestamp does not match the current X server configuration
+	timestamp. Usually this means that the output configuration has
+	changed since the timestamp was received by the application.
+
+	InvalidTime indicates that the supplied output reconfiguration time
+	is earlier than the most recent output reconfiguration request.
+	Generally this indicates that another application has reconfigured
+	the output using a later timestamp.
+
+	Failed is returned whenever the operation is unsuccessful for some
+	other reason. This generally indicates that the requested output
+	configuration is unsupported by the hardware. The goal is to make
+	these limitations expressed by the protocol, but when that isn't
+	possible it is correct to return this error value. If, as a
+	implentor, you find this error code required, please submit the
+	hardware constraints that exist so that a future version of the
+	extension can correctly capture the configuration constraints in
+	your system.
