text: Time could be defined as a dimension.  We are always subconsciously aware of this time. We use it to define how long things would take. For example we can say that an x program will last for about an hour. So my definition of time would be that it is used to define how long a specific thing or event would take or took. And as long as you are on the earth and not moving really fast, you can say that it is constant meaning the same every where. I don't mean to say that 1 p.m. here is 1 p.m. everywhere. But I mean that an hour here is hour everywhere on earth.
