One can easily observe this &quot;server is the actual game&quot; property in Minecraft when running on an underpowered server.<p>At home, Minecraft runs on my home server (with a small Athlon CPU) and it fails to keep up with the required speed of the game, so the server log will show messages like &quot;server clock running behind, skipping 58 ticks&quot; every so often.<p>An observable effect of this is that you have to hold the right mouse button just a little bit longer than the actual animation when eating stuff. And when you look at the sun, you will see it moving forward continuously (as calculated by the client), but skipping back a tiny bit every few seconds (when the client adjusts for the server&#x27;s time drift).
