So Spaceflight 101 said the LOI was on Dec 6 at 2:30 UTC. More recently Zarya says 9:30 UT based on 112 hour flight time.
An update: Apparently Chang'e 3 is working well. December 3 correction, that everyone was asking, has been completed successfully. A third correction isn't needed. http://www.readdailynews.com/news-5952303-Chang-E-III-has-flown-nearly-350000-kilometers-without-3rd-halfway-correction.html
There are lots of funny mis-translations like that in Google, especially for Chinese and Japanese (I remember Hayabusa's name was always translated by Google as "It is quick the").There is a word, “落月” that keeps showing up in Google translations as "sangrakwol", which is meaningless. Can anyone say what this actually means in the context of Chang'e? It is found in the second paragraph of this article: http://tech.sina.com.cn/d/2013-12-02/02398965861.shtml
LOI was completed at 09:47 UTC.
