- Mar 17, 2026 Clock Domains and the Ordering of Events Across Hosts Why timestamps from two machines cannot be subtracted to get a latency, what NTP slewing and stepping do to a span duration, and how causal order survives without a shared clock. observability
- Sep 19, 2025 Time Namespaces and the State That No Namespace Covers How a time namespace shifts the monotonic and boottime clocks without changing the wall clock, and which kernel resources remain global no matter how many namespaces a process joins. operating systems
- Nov 12, 2024 Clock Sources and the Resolution Floor of a Timing Call How monotonic clocks, TSC reads, and syscall-based time differ in cost and granularity, why a measured interval is a difference of two uncertain readings, and how the floor limits what a benchmark can resolve. performance engineering
