The LHC experiments, test beam installations and the LHC machine beam instrumentation need to operate synchronously with the timing signals used by the two LHC rings. These timing signals are encoded and broadcast over optical fibres to all the required points by the Timing, Trigger and Control (TTC) system. The TTC also provides the internal distribution of timing within the experiments, to which trigger and local synchronous commands and data are integrated. The resulting encoded signal is sent to thousands of destinations within the experiments' front-end and data acquisition systems. After an overall description of the TTC system, this talk will give the present status of the installation and will outline the necessary changes intended to suit it for future operations.
