It's Time
It's a widespread notion that time moves faster whenever one does something they enjoy and slower when they do something they don't like.
Many people have different ways of coping with the latter. For example, in school, students realize that constantly looking at the clock seems to make it tick slower, so they pretend not to care so that it passes by faster.
Others try to find a silver lining in the grueling task they are performing so that they start to enjoy it to make it flow faster. Others do it in the presence of those they are comfortable around. Some listen to music or just some form of background noise in general.
The point is that everyone has ways of making the time 'move faster' when it seems to move slowly, and this beast tide was no different.
As the days passed, the citizens grew tenser. Every explosion, every salvo released by the turrets, every flash of orange caused by a flame turret activating, and so on. Every sound made them grow tenser.
