I will give one interesting example for this.
Let’s imagine a scenario a person is preparing for his academic examinations. He has only 1-hours left for exam to start, but he is not confident and he didn’t prepare well. If he writes the exam he will sure fail. He needs at least 4 days to prepare. If he fails he needs to wait for another year to write the exam. Now he sits in the cabin and decreases the relative time-flow rate by 1/96 that means 1hours equal to relatively 4 days. Now he has enough time to prepare for his examinations. In this case he saves approximately 1year by using his future 4days. But he becomes 4 days older to his actual age. That means he saved 365-4 = 361 days.
Same logic can be extended to space. I will talk about this later.
According to special relativity the above scenario can be possible. But I talked about stationary cabinet. This is Einstein special relativity formula for calculating time dilation.
In this case object has to move very high speeds to get sufficient ∆t'
