We know that time flows from the past to the future. We remember the past and make predictions about the future. You stir cream in your coffee, and it mixes in. It doesn't un-mix.
The classical understanding of the nature of time is that time is absolute - that time ticks by the seconds, minutes, hours, and years at the same rate for everyone.
The directionality of time comes from the idea in classical physics called the 'second law of thermodynamics', which states that a quantity called 'entropy' (which is a measure of the disorder of a system) always increases.

Similar ideas to We see time as absolute
The second law of thermodynamics, the so-called 'the entropy law', it is said to be one of the most important laws in nature. This law states that entropy, which is a measure of disorder in a closed system, almost always increases in time.
If one looks at reality on the smallest scale, using equations of quantum gravity, time vanishes. However, we still perceive time as moving forward sequentially.
Key aspects of time are described by the second law of thermodynamics, which states that heat always passes fro...
