Reflecting on Time

I saw the movie Interstellar last weekend and ever since, I've been thinking about time and wonder if it exists as a 5th dimension. Bendable, recursive, wormholes...

So what time is it here - a quarter after 8 or a quarter before 4?

...or maybe it's constant and when you see time in a reflection, it is the other side of the 5th dimension...

Things to ponder. The movie was good, a little long in the tooth, but got me thinking.
