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
