Hypertext Time Protocol

Hypertext Time Protocol is a time synchronization tool that uses Web server responses (HTTP headers) instead of the NTP protocol. It works through proxy servers and with HTTPS sites. It is especially useful for strongly firewalled machines: for ntp to work, you must have access to incoming and outgoing packets from UDP port 123. In most corporate environments this is not the case, but as long as HTTP or HTTPS connectivity is available, you can use htp.
