Making every timestamp trustworthy at Arcadia Markets, an exchange operator with MiFID II RTS 25 clock-sync duties across 40,000 hosts and three clouds: the case that collapsed because the firewall's clock ran 40 seconds fast, putting the cause after the effect; the rebuilt time hierarchy with two GNSS grandmasters, PTP to the matching engines within 100 microseconds of UTC and NTS or chrony to every other host; and the eight-station clock rail from time as evidence through sources, discipline, timestamp semantics, skew, drift at scale and forensic assurance to programme optimisation.

Telemetry Time Integrity — The Clock Rail

An expert-level course in programme optimisation for time synchronisation itself: making every timestamp in a global exchange operator's telemetry estate trustworthy, traceable, verifiable, and defensible. Work the clock rail across time-as-evidence requirements and threats, time-source architecture (NTP, PTP, GNSS), clock discipline across fleets and clouds, timestamp semantics in pipelines, time zones/leap seconds/skew, detecting and correcting drift at scale, forensic and legal time assurance, and programme optimisation with continuous verification.

What you'll learn

  • Establish time-integrity requirements and a clock-manipulation threat model mapped to MiFID II RTS 25, FINRA CAT, PCI DSS 10.6, ISO 27001 A.8.17, and NIST SP 800-92.
  • Design a stratum hierarchy with GNSS-disciplined grandmasters, deliberate PTP/NTP/NTS choices, redundancy, holdover, and a consistent leap-smearing policy across on-premises and cloud.
  • Discipline every host class - Linux, Windows, VMs, containers, Kubernetes nodes, network devices, and IoT/mobile endpoints - to that architecture with per-class drift budgets.
  • Fix timestamp semantics through the pipeline, handle time zones/leap seconds/skew by policy, detect and correct drift at scale, and assure time forensically with RFC 3161 trusted timestamping and expert-witness-grade documentation.
