位置 | 标志 | 含义 |
remote之前 | * | 响应的NTP服务器和最精确的服务器 |
+ | 响应这个查询请求的NTP服务器 | |
blank(空格) | 没有响应的NTP服务器 | |
列表上方 | remote | 响应这个请求的NTP服务器的名称 |
refid | NTP服务器使用的更高一级服务器的名称 | |
st | 正在响应请求的NTP服务器的级别 | |
when | 上一次成功请求之后到现在的秒数 | |
poll | 本地和远程服务器多少时间进行一次同步，单位秒， 在一开始运行NTP的时候这个poll值会比较小，服务器同步的频率大，可以尽快调整到正确的时间范围，之后poll值会逐渐增大，同步的频率也就会相应减小 | |
reach | 用来测试能否和服务器连接，是一个八进制值，每成功连接一次它的值就会增加 | |
delay | 从本地机发送同步要求到ntp服务器的往返时间 | |
offset | 主机通过NTP时钟同步与所同步时间源的时间偏移量，单位为毫秒，offset越接近于0，主机和ntp服务器的时间越接近 | |
jitter | 统计了在特定个连续的连接数里offset的分布情况。简单地说这个数值的绝对值越小，主机的时间就越精确 |
