NTP Packet Parser

JSON →
library 0.5.0 ·javascript
verified May 27, 2026

This library provides a utility for parsing Network Time Protocol (NTP) UDP response packets into a structured JavaScript object. It adheres to RFC 5905, focusing solely on data extraction rather than time validation or calculations. The current stable version is 0.5.0, with a release cadence that generally follows Node.js LTS cycles, providing support for Node.js 18, 20, and 22. It is actively maintained with recent updates addressing Node.js compatibility and dependency bumps. Its primary differentiator among NTP parsing utilities is its singular focus on robust packet parsing, providing a structured representation of all standard NTP fields without imposing further logic, leaving time synchronization calculations and network interactions to consumer libraries. This strict separation of concerns makes it a reliable low-level building block for higher-level NTP client implementations.
