The LHC central timing has been deployed in 2008 for the LHC startup. It fulfilled its job well during the short phase of the LHC startup and in the dry runs performed since then. However, as it was developed in a very short time to be operational for the LHC startup, a review and consolidation was now required. The main objectives of this consolidation are to be proactive by finding the weak points and making the system more robust, to document the software and the hardware, to put in place a testing and deployment strategy, and to reduce intervention time. This presentation will explain the LHC central timing system, and give a progress report on its consolidation.
