Actually, time is just the duration between first event and second event. For example say the duration between one gets up in the morning and goes to bed or duration between the first world war and the second world war, or the duration between the beginning of first creation of God and today's ceration of God. The duration between one gets up in the morning and goes to bed in the night remains only between one gets up in the morning and one goes to bed in the night. So, that time remains there only and doesn't go anywhere. Moreover, as that duration doesn't change, time doesn't change.
