Why NTP Falls Short and How PTP (IEEE 1588) Achieves Sub‑Microsecond Sync

This article explains the limitations of NTP for clock alignment, introduces the Precision Time Protocol (PTP) and its IEEE 1588 versions, describes the master‑slave hierarchy, hardware timestamping, and why PTP delivers far higher synchronization accuracy for networked devices.
