Days and Time began on DAY ONE of the Creation WEEK when the LIGHT was created. The orbs, (sun, moon and stars), were created on DAY FOUR to transmit the LIGHT that was created on DAY ONE. For example, the LIGHT is Energy created from the Power Source Yah, and the Light is transmitted to the orbs that are like Substations; the sun distributing Bright Light by DAY and the moon and stars distributing Medium to Low Light by NIGHT. The function of the orbs are to distribute the Light Energy that was created on DAY ONE:
Genesis 1: 3-5 And God said: 'Let there be light.' And there was light. 4 And God saw the light, that it was good; and God divided the light from the darkness. 5 And God called the Light Day, and the darkness He called Night. And THERE WAS EVENING AND THERE WAS MORNING, DAY ONE.
