Sometimes the NTP port can be blocked (such as at Universities). This script(s) allows the raspberry pi to still have the correct time without going through the NTP port. Theoretically, this script should work anywhere in the world pending that https://time.is and https://wikidates.org are not blocked for any reason.
If your distribution has an /etc/rc.local file then it should install correctly.
This package depends on lynx.
sudo apt-get install lynx -y
git clone https://github.com/fornitsumfornis/Workaround-For-When-the-NTP-Port-is-Blocked
cd Workaround-For-When-the-NTP-Port-is-Blocked
chmod 755 install.sh
sudo sh install.sh
