Raspberry pi wont update time on NTP

Weird problem with a pi zero-w, where when I put it on my friend's network it gets the wrong time.


Bit of a workaround, rather than a fix, but it got me up and running, and should be reliable...

1. Open rc.local file
   sudo nano /etc/rc.local
2. add following line to the rc.local file
   sudo date -s "$(wget -qSO- --max-redirect=0 google.com 2>&1 | grep Date: | cut -d' ' -f5-8)Z"
3. reboot the Rpi
   sudo reboot

Basically, it gets the HTTP headers from the server at google.com and sets the pi's time to that.
