The timing system at the Spallation Neutron Source (SNS) has recently been updated to support the long range production and availability goals of the facility. A redesign of the hardware and software provided us with an opportunity to significantly reduce the complexity of the system as a whole and consolidate the functionality of multiple cards into single units eliminating almost half of our operating components in the field. It also presented a prime opportunity to integrate new system level diagnostics, previously unavailable, for experts and operations. These new tools provide us with a clear image of the health of our distribution links and enhance our ability to quickly identify and isolate errors.

The ubiquitousness of web clients from personal computers to cell phones results in a growing demand for web-based access to control system data. At the Oak Ridge National Laboratory Spallation Neutron Source (SNS) we have investigated different technical approaches to provide read access to data in the Experimental Physics and Industrial Control System (EPICS) for a wide variety of web client devices. We compare them in terms of requirements, performance and ease of maintenance.
