Please do this only if you trust everybody on the network! Here i am using Raspian_For_Banana Pi_v3.1 on a Banana Pi.
#disable auth #broadcastclient , monitoring the network traffic and more carefully reading the fine print of NTPd docs, I realized that NTPd requires unrestricted access to UDP port 123 for both outgoing and incoming traffic. The reason for the -7294 sec offset was that the /etc/init.d/ntp script was starting the /var/lib/ntp/dhcp as the config file for ntpd (-c), this file was using 192.168.0.1 as timerserver.

I started digging and found out that the NTPd service is not updating the local time.
This is most likely only a recent problem since I had power failures before and never noticed problems with time. When I stop the service and run ntpd manually May 5 autohome ntpd: ntpd [email protected] Fri May 18 UTC 2012 (1) May 5 autohome ntpd: proto: precision = 1.000 usec May 5 autohome ntpd: Listen and drop on 0 v4wildcard 0.0.0.0 UDP 123 May 5 autohome ntpd: Listen normally on 1 lo 127.0.0.1 UDP 123 May 5 autohome ntpd: Listen normally on 2 eth0 192.168.1.120 UDP 123 May 5 autohome ntpd: peers refreshed May 5 autohome ntpd: Listening on routing socket on fd #19 for interface updates # /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help driftfile /var/lib/ntp/ntp.drift # Enable this if you want statistics to be logged.
Troubleshoot the problem further by identifying why the client cannot communicate with the WSUS server using HTTP. If you can reach the WSUS server, verify that the client is configured correctly.
If you are using Group Policy settings to configure Windows Update, use the Resultant Set of Policy (RSOP) tool (Rsop.msc) to check the computer’s effective configuration.

Since this is not something I'm willing to do on my network, I uninstalled the Also had problems with ntpd syncing, got an offset of -7294 seconds after reboot and ntpd was not able to sync up. Which is my internet modem with a timeserver which had -7294 seconds offset.
