“No one knows where time began and where it ends, and it is time only which can keep a record of the creation, maintenance and destruction of the material manifestation. This time factor is the material cause of creation and is therefore a self expansion of the Personality of Godhead. Time is considered the impersonal feature of the Lord.” (Shrila Prabhupada, Shrimad Bhagavatam, 3.10.11 Purport)
