System and method for setting time and date in a device without access to network time protocol

A system and method for setting time and date in a device (e.g., a set top box (614), or similar client device) through a network connection when a network time standard server (606, 620) (e.g., a NTPserver) is unavailable (e.g., blocked or blacklisted) are provided. The system and method of the present disclosure involves sending (404) a request over a network from a device for information froman Internet address (618), receiving (406) a packet (500) from the Internet address (618) in response to the request, extracting (408) time and date information from a header (502) in the packet (500), and using the extracted time and date information to set (416) the current time and date for the device. 提供了种用于在网络时间标准服务器(606，620)(例如，NTP服务器)不可用(例如，被封锁或列入黑名单)时通过网络连接设定设备(例如，机顶盒(614)或类似的客户端设备)中的时间和日期的系统和方法。本公开的系统和方法涉及通过网络从设备发送针对来自互联网地址(618)的信息的请求(404)、从互联网地址(618)接收响应于该请求的分组(406)、从分组(500)中的头部(502)提取时间和日期信息(408)、以及使用所提取的时间和日期信息来设定设备的当前时间和日期(416)。
