So what is time?

So, what is time?

I no one asks me, I know:

If I want to explain it to a person who asks, I do not know anymore and yet, I affirm with certainty that,

had nothing passed, there would be no past time – had nothing happened there would not be future time,

had nothing existed, there would be no present time.

St. Augustine

Entonces, qué es el tiempo?

Si nadie me pregunta, yo lo sé:

Si lo quiero explicar a la persona que pregunta, no lo sé y aún así afirmo con certeza que,

si nada hubiera sucedido, no habría tiempo pasado – si nada pasara no habría futuro,

si nada existiera, no habría presente.

St. Augustine
