The sun was making exaggerated.... Flowery language to attempt to show how clever he is without any actual substance.
It is colorful language, but I don't feel that he's attempting at being clever, it's a creative way of saying it's getting late.
Oh here's an awesome thing:

tl;dr version: A better way of saying it's getting late would have been, shockingly, 'it's getting late'.
(i) Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.
(ii) Never us a long word where a short one will do.
(iii) If it is possible to cut a word out, always cut it out.
(iv) Never use the passive where you can use the active.
(v) Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.
Writing it in some over the top convoluted way like that just because you think it shows the reader how clever and creative you are is generally the wrong road to be going down unless you're spectacularly masterful at it. You're writing the book to convey your story, characters and world to the reader, not to impress them with flowery ways of describing things.
What does using that phrase actually accomplish? Does it convey any particular image of HOW the sun is setting? Or is it just setting exactly like a sun sets? No image is conveyed, no insight is gained, it's just pointless fluff that makes reading the book take a little longer and doesn't help the reader get a clearer image of what's happening in the story at all.
This is basically amateur writer mistake #1 and shows a complete misunderstanding of the entire concept of good writing.
Despite the liking ZP comment, otherwise I'm 100% behind OANST and consider him 100% correct in this thread. Not just me who thinks so, GEORGE ORWELL agrees. ;D
