- Aug 15, 2026 Wall-Clock Timestamps Do Not Order Distributed Events Why two machines reading the same instant produce different numbers, how far the disagreement grows between synchronizations, and what an interval-bounded timestamp can still support. distributed systems
- Apr 22, 2026 Mapping RTP Clocks to Wall Time for Cross-Stream Synchronization Sender reports tie an RTP timestamp to an NTP instant; using that correspondence to align audio and video exposes clock offset, drift, and the limits of the mapping. internet protocols
- Jan 26, 2026 The NTP Four-Timestamp Exchange and Its Asymmetry Limit How four timestamps yield an offset estimate, why the estimate is only as good as the path symmetry, and how the protocol decides which of several servers to believe. distributed systems
- Dec 5, 2025 One-Way Delay and the Clock Offset Problem Why a one-way delay measurement needs synchronised clocks, how a constant offset biases the result, and how two-way exchanges bound the error. networking
- Apr 26, 2025 Clock Skew and the Limits of Cross-Host Event Ordering Where host clocks diverge, how much error an unsynchronized timeline carries, and which ordering conclusions survive when timestamps from different machines are merged. security
