Metaphors of time

I have found a site that has given me some multiples metaphors surrounding time. I was advised by Alan to take a look at some to enhance my research and direction for the characters.

For example I found this:

"Time Is a Storm
Time is a storm in which we are all lost. Only inside the convolutions of the storm itself shall we find our directions."
(William Carlos Williams, Introduction, Selected Essays)

Now this is interesting because it gives me a field to work with. I can see Time as a storm which leads to chaos and distruction. So from this it would be an evil character with some form of essence that makes it impossible to escape. I can always interpret the "Only inside the convolutions of the storm itself  shall we find out directions" as a form of weakness that time can have; a way out.

Another interesting one is:

Time Is a Prison
Initially, I was unaware that time, so boundless at first blush, was a prison.
(Vladimir Nabokov, Speak, Memory)

This again would lead me to think of an evil character but maybe not even a character, maybe a structure - depending on how it can go.

"Time Is a TeacherTime is a great teacher, but unfortunately it kills all its pupils."

This metaphor reminds me of an erosion, or a slow killing as time passes.

There are other metaphors that I could work with but these are my favourites at the moment.
