This paper explains the distribution of time and provides a brief overview of various dissemination services. While there are several dissemination services available, this paper focuses on time dissemination using the Network Time Protocol and its network performance. The various time dissemination services available, as well as their methodologies, are discussed. The Round Trip Time and Offset for various NTP servers are investigated. These servers are distributed with time stamps and are located in geographically diverse locations around the world. The jitter in the Round Trip Time and Offset for various NTP servers is also investigated. The paper focuses on the performance of various NTP servers in terms of RTT and Offset.

本文解释了时间的分布，并简要概述了各种传播服务。虽然有多种传播服务可用，但本文重点关注使用网络时间协议的时间传播及其网络性能。讨论了可用的各种时间传播服务及其方法。研究了各种 NTP 服务器的往返时间和偏移量。这些服务器带有时间戳，分布在世界各地的不同地理位置。还研究了各种 NTP 服务器的往返时间和偏移量中的抖动。本文重点介绍了各种 NTP 服务器在 RTT 和 Offset 方面的性能。
