Ireland has taken a major step towards bolstering its digital economy by introducing the country's first National Timing Grid. This groundbreaking initiative aims to establish a resilient timing infrastructure by interconnecting independent atomic clocks across the nation in real-time. These highly accurate clocks provide precise time measurements, exceeding the capabilities of conventional clocks.

Enhancing Precision and Stability
The National Timing Grid incorporates six caesium atomic clocks supplied by prominent Irish telecommunications companies. These clocks are synchronized via GPS satellites, forming a comprehensive network. As of now, the grid already includes four connected atomic clocks, with plans to expand further. The interconnected clocks continuously track and compare their stability, enabling early detection of timing drift, which could impact critical infrastructure.

Securing Against GPS Jamming and Spoofing
The establishment of this timing grid also serves a crucial security purpose. It acts as a defense against GPS jamming and spoofing, where the integrity of GPS signals is compromised. By utilizing the grid's accurate time measurements, Ireland can safeguard its critical systems and infrastructure from potential disruptions caused by signal interference.

Driving Growth in the Digital Economy
The National Standards Authority of Ireland (NSAI) and its National Metrology Laboratory have spearheaded the development of this strategic initiative. Local companies, Timing Solutions and Data Edge, have also played instrumental roles in its implementation. The NSAI notes the significance of precise timing for the digital economy's expansion, particularly in sectors such as communications and financial services. Furthermore, with the launch of the National Timing Grid, Ireland has attained official recognition for its timescale known as UTC (NSAI).
David Fleming, the NSAI's technical manager for time, emphasizes the importance of maintaining accurate timing in enabling seamless online services: "Keeping Ireland's networks on time is crucial in supporting its day-to-day operations as more and more of our services are moved online."
