ESMA consultation paper Annex B Regulatory Technical Standard (RTS 25) on MiFID II
• Requires customers’ clocks and clocks of trading venues to be synchronized
• Standardizes the recorded time for post-trade data, transaction reporting and order event auditing
• Level of accuracy for operators of trading venues requires 1ustimestamping
• Level of accuracy for members or participants of trading venue activity using high-frequency algorithmic trading technique requires 1us timestamping
• Any other trading activity requires 1ms timestamping or better
Smarter Grid Solutions has come up with a key enabling technology that will create flexibility in electricity distribution networks and allow more renewable energy to be connected to the grid
• Time sync to monitor and control the SG with accuracy req. from 1sec to 1usec

Source for precise time: Global Navigation Satellite System (GNSS)
• A billion euro investment
• Maintains highly accurate UTC
• Available to everyone
• Vulnerable source

GNSS as a single point of failure …
• Interferences
• Intentional (jamming), unintentional
• Multipath, spoofing, GNSS outages
• Atmosphere (solar activities)
• Indoor and outdoor (urban canyons)

Customer portal for monitoring timing services at demarcation
• Sync portal is a web-hosted application
• Custom views, reports per customer/carrier
• Data segregation ensures privacy between customer domains
• Data collection via FSP NM or via dedicated collector appliance

Takeaways
• The importance of time in communication networks is increasing
• Building blocks are available to architect and operate an
independent system to maintain and distribute precise time data
• TaaS means SLAs and a backup to GNSS
