A function created by humans to account for periods during each day, measurable and quantifiable so we can apportion out our daily tasks.
But does time really exist?
My angels have told me that time is a concept only used on earth. As such, time as a linear means of calculation does not exist anywhere else in the universe and humans find it very difficult to grasp the idea of a 'timeless' environment and space.
Time is relative and I often find myself asking my angels to help me with more or less time as needed, after all we all remember those long afternoons in school when time dragged on and on.
