Vishnupurana 2.8.p5

2.8.p5

O Maitreya, while in one insular continent the sun shines in midday, in the opposite Dwipas it will be midnight; rising and setting thus take place at all seasons and are always opposed in the different cardinal and intermediate points of horizon. Wherever the sun is visible he is said to rise there and wherever he disappears from view he is said to be set. In sooth, their is neither rising nor setting of the sun; for he always exists; the appearance and disappearance of the sun are merely called rising and setting.
