ELI5: why is it important to specify the "time of death"?

When someone dies on a tv show, for example, and they mark the exact time of dying. Why does it matter? Does it actually happen?

Time of death or its approximation is important for figuring out how long... welll... they've been dead. 

If the coronor says the body has been dead for 6 hrs and its 2 AM, that puts the time of death at 8 PM... which if you're a suspect who now needs to have an alibi for where were you at approx. 7:30-8:30 pm, it matters a great deal.
