The sun is used in a temple to tell time. They don't have clocks or cell phones, they have sun dials and good old fashioned "looking up and seeing where the sun is right now."
This also can mean o' clock, as in "five o'clock" It's used when measuring what time it is in Japanese.
Time in a temple makes you think of Jesus (じ). Specifically, Jesus being able to perform time travel magic. He winks at you, goes back to the dinosaur ages, where he wrestles a T-rex. Then, he goes to WWII era and punches Hitler in the mouth.
