Tailored specifically for UK legal practitioners, this practical technical reference addresses a critical vulnerability in modern litigation: relying solely on visible document dates and uncalibrated system clocks that quickly collapse under adversarial scrutiny. Digital event records scattered across an enterprise estate are inherently prone to time zone discrepancies, clock drift, and conflicting field semantics. To transform disjointed artefacts into robust court evidence, the text sets out the complete methodology for multi-source timeline construction. It covers raw event sources including device artefacts, platform audit logs, counterpart records, network layer traffic, physical-world systems, and recoverable deleted data. Legal teams learn the precise mechanics of normalising timestamps to UTC, establishing line-by-line corroboration, and assigning explicit confidence levels to ensure master chronologies withstand court challenges. Beyond core technical construction, the publication provides actionable presentation strategies, practical worked examples, drafting aids, interrogatory questions for clients, opponents, and e-Discovery providers, and red flag checklists detailing precisely when an ISO 17025-aligned digital forensic expert must be instructed.

§ 13 · COMMON QUESTIONS Frequently asked questions Why can't we just build the chronology from the documents' visible dates? What does "normalising to UTC" actually involve? How precise are digital timestamps really? The other side's chronology contradicts ours. How is that resolved? Can a timeline prove who did something, or only when it happened? When should timeline work start?
