Oh Please Time is a human endeavour to explain stars and planets and well, capitalist hourly wages.
Time as we view it today remains a hypothetical construct. Yeah really. Good grief people only began owning watches 100 years ago (maybe a bit more) you know the pocket watch, then wrist watch. Why? Because of the industrial revolution. Things needed to have a measure other than sunrise, high noon and sunset. No hokus pokus Bible stuff in time at all. The trains (I blame the Brits for this) had to run on a schedule. Otherwise pile ups would abound.
Bible time was nowhere near accurate. These were a group of nomads and their stories. A blink of an eye could mean after your eyes shut to sleep and then when they opened. There is no consistency in Bible time keeping. Why? Because the damn book wasn't meant to be used scientifically. Seasons and holy days were established by constellations . You know the earth turns and different constellations and galaxies and planets become visable. So then you know okay its time to celebrate the end of harvest and the beginning of hunting season. These people always had their heads in the clouds.
I guess by the question "God and the concept of time" a simple explanation would be that both are human construction to order a society. Of course I'm just guessing.
