htpdate

Htpdate is a command line tool designed for time synchronization over the HTTP protocol. It allows users to synchronize their system time by querying time servers on the web. The tool was developed to provide a lightweight and accurate alternative to traditional time synchronization methods. Htpdate uses the HTTP protocol to send HTTP GET requests to time servers and parse the response to obtain the server time. By comparing the server time with the system time, htpdate calculates the time difference and adjusts the system clock accordingly. One of the key features of htpdate is its ability to handle network delays and uncertainty in the server response time. It incorporates a statistical algorithm to estimate the best server time among multiple time server responses. The tool also supports proxy servers, which enables users to synchronize time even when they are behind a firewall. Htpdate is available for various operating systems, including Linux, FreeBSD, and Windows. Overall, htpdate is a reliable and efficient command line tool for accurate time synchronization over the HTTP protocol.
