Time keeping is crucial for security, privacy, and anonymity. Sdwdate is a Tor friendly replacement for rdate and ntpdate that sets the system's clock by communicating via onion encrypted TCP with Tor onion webservers.
At randomized intervals, sdwdate connects to a variety of webservers and extracts the time stamps from http headers (RFC 2616). Using sclockadj option, time is gradually adjusted preventing bigger clock jumps that could confuse logs, servers, Tor, i2p, etc.
This package contains the sdwdate time fetcher and daemon. No installation on remote servers required. To avoid conflicts, this daemon should not be enabled together with ntp or tlsdated.
