NTP: Synchronise Your Watches

Just like an old fashioned grandfather clock, time time on your computer’s clock can slowly drift. You can quickly verify the accuracy of your clock by comparing it to https://time.is/. It’s not unusual for it to be anything from a few seconds to a couple of minutes out. For most purposes this is not a major issue, but there are some applications which are very time sensitive. NTP (Network Time Protocol) is a tool which will synchronise your computer’s clock with a network of accurate time servers, ensuring that it’s always accurate. There’s a lot to be said about NTP, but this is a quick guide to getting it up and running on an Ubuntu machine.
