Well, I of course don't really know... but I'm assuming you asked everyone because you want us to guess. If not, I'm sorry for wasting your time.
The human brain is wired to see patterns and group things together. This explains paranoid schizophrenics (with an increased logical awareness) and stereotypes like racism, sexism, bigotry, etc. (we label groups of people as threats) all to make sense of our environment. It probably started out as a great survival tool in nature, but, ironically, plagues us in society.
Let's see. 12:10am is when you wake up at night with a reoccurring nightmare involving you going blind, dying, or your teeth falling out. These all just guesses, based on Freudian psychoanalysis.
It very well could be an important date in history, instead of a time at night.
Alternatively, 1210 might be your favorite number because it's like counting up then down... 1... 2... then 1 again... then 0.
Hope this helps :)
