Without events, there is no time

I think this means that we use events to mark the passing of time. Without the beginning, progression and ending of an event we have no sense of time passing. We need events, even the simplest, to mark time because without them we have no sense of time. We mark time with clocks through the 'event' of the hands moving around it. Sundials mark time according to the rising and setting of the sun. Everything that happens is an event, even the smallest, unnoticed, or everyday occurrence. If everything stopped and no events occurred, as if pausing the TV, would there be time or would we just not know about it?

A photograph can capture a moment of an event, but not an entire event. Photographs freeze the event within the time the picture was taken. A sequence of photographs can document an event. Looking at a single photograph is like looking at the paused TV. We know time passed before and after the moment in the picture because we know time is needed to take the picture. The taking of the picture is an event in itself, which could not happen without time. Photography cannot exist without time and time cannot exist without events, so without events there is no photography.

A thought on photographs and memory: When we have a photograph, but we do not remember the event shown, the photograph becomes an example of a time period. We can't remember the moment every picture was ever taken of us, especially when we were children. A picture of me as a child with my sister and our dog shows me a time in my life, it brings back memories of other events during childhood. For me, this picture does not capture a specific event, but triggers memories of a certain time, which I can remember.
