I'm working on a university exam taking application and needed to make sure the clock on the server was properly set so students don't get upset that they didn't make the due date.
When I checked the server clock, it was correctly set for the time zone, daylight savings time and hour, but the minutes were off.
A couple of google searches talked about syncing the server with a server pool. That sounded pretty complicated, but time has to remain correct, right??
It actually turned out pretty simple. I used this blog article, but it boils down to a few easy steps:
sudo apt-get install ntp
Yep, that's it. You can change the config for the server pool if you like (see blog above), but that's pretty much it!
