A comprehensive open-source book on the Precision Time Protocol (IEEE 1588/gPTP). From thought experiments to protocol internals, LinuxPTP source code analysis, and a hands-on ptp-lite implementation (~1000 lines C). A complete guide from theory to running code.

A precision timing control room for building, observing, measuring, and tuning multi-hop PTP clock cascades on one Linux host.

Interactive gPTP / IEEE 802.1AS & AUTOSAR STBM time-synchronization visualizer for automotive Ethernet — animates Sync/Follow_Up/Pdelay, offset & path-delay math, HW vs SW timestamping, and a PI frequency servo (syntonization). Vanilla JS, no build.

PTP configuration and monitoring dashboard for OpenShift — visual clock topology, telco-reference templates, solver-assisted PtpConfig creation, and live metrics.
