I will only say this. One day in the last 10-15 days you may have stepped outside and to your surprise it was not dark as it was the day before it. You probably said to yourself "wow I wonder why it is not dark today as it usually is this time of the day". Then you went on your way. You had just recognized a 12 - 15 minute time difference that most did not notice. If you understand cause and effect you know this time shift should not be taken lightly.
