SNTP uses the standard NTP timestamp format described in RFC-1305 and previous versions of that document. In conformance with standard Internet practice, NTP data is specified as integer or fixed-point quantities, with bits numbered in big-endian fashion from 0 starting at the left, or high-or...
Root Dispersion: 单位是 NTP Short Format Reference ID: 32 比特指示服务端的参考时钟 (即上层服务器信息). 即上层时钟源 . 当阶层为 1 时, 那么上层是原子钟等设备. 没 IP, 所以使用 ascii 字符 从阶层 2 开始, 表示 IP 地址. Reference Timestamp: 指示服务端自身系统时间最后一次被设置的时间戳.通常...
SNTP is abbreviation for simple network time protocol. At present it is an important engineering method for time synchronization in Internet. This paper describe principle,mode,timestamp format,message format of SNTP, finally we give some advice for application. Key words: SNTP; time synchronization ...
corrected, in NTP timestamp format. Origin Timestamp (org) ---> T1 Origin Timestamp (org): Time at the client when the request departed for the server, in NTP timestamp format. Receive Timestamp (rec) ---> T2 Receive Timestamp (rec): Time at the server when the request arrived fro...
用法:gmtime()、localtime()、strptime()等函数返回的元组格式的时间。里面的值可以通过索引或者属性名称访问。 9、时间转化的几个函数 datetime类的使用 timedelta对象 用法:两个时间之间的间隔(秒) date对象 用法:处理年、月、日 类方法: date.today()方法:返回当前本地时间,等价于 date.fromtimestamp(time.tim...
Reference Timestamp 64比特 本地时钟最后一次被设定或更新的时间。如果值为0表示本地时钟从未被同步过。 Originate Timestamp 64比特 NTP报文离开源端时的本地时间。 Receive Timestamp 64比特 NTP报文到达目的端的本地时间。 Transmit Timestamp 64比特
NTP Packet Format NTP Fundamentals Figure 2-26 shows the NTP message exchange process. Figure 2-26 NTP message exchange process The NTP message exchange process is as follows: The NTP client sends an NTP request message to the NTP server. The NTP request message is timestamped as T1 when ...
Originate Timestamp: NTP请求报文离开发送端时发送端的本地时间, 长度为 64 Bits. Receive Timestamp: NTP请求报文到达接收端时接收端的本地时间, 长度为 64 Bits. Transmit Timestamp: 应答报文离开应答者时应答者的本地时间, 长度为 64 Bits. Authenticator(Optional): 验证信息, 长度为 96 Bits, (可选信息...
getByName(NTPTimeServerUrl); TimeInfo timeInfo = timeClient.getTime(timeServerAddress); TimeStamp timeStamp = timeInfo.getMessage().getTransmitTimeStamp(); Date date = timeStamp.getDate(); DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); dateTimeMessage = dateFormat....
NTP是网络时间协议(Network Time Protocol,简称NTP),是一种用于同步计算机时间的协议。NTP服务器指的是提供NTP服务的计算机或设备。NTP服务器的主要功能是保证网络上的所有设备的时间同步,以确保各个设备相互之间的时间协调一致。NTP服务器通常连接到具有高度精确时间源的设备,例如:GPS接收器或原子钟,以确保提供准确如一...
