| Zusammenfassung | Laboratory sources for standard-frequency and time which receive external time signals to control their built-in oscillators are widely used wherever accurate and stable frequency and time, optionally with universal synchronization, are required. We propose a method to obtain traceability of such signals to Coordinated Universal Time (UTC) and particularly to UTC(PTB), its realization by the Physikalisch-Technische Bundesanstalt. The role of PTB’s weekly published Time Service Bulletin is discussed in detail, and the metrological steps for establishing and maintaining traceability are described and uncertainty contributions are stated. Furthermore, we discuss how to possibly meet financial sector regulations according to European MiFID II. A procedure as a component for the assessment to provide accurate time through telecommunication networks using e.g. the Network Time Protocol (NTP) is presented. It checks outputs of an NTP server to validate that its time reference and provided time-of-day information is in accordance with specific requirements. |
