The OP has not shown any signs of be cryptic of even that smart. He has just been supposedly reading things of the DED. At times even admitting he doesn't understand what he is reading. Given that, i don't think he is giving us anything with the 21:30 33 post.

I do think he is ...
Remember yesterday they were locked up in the office,
maybe they are or he is restrictedand summond to not give any more info ...
If he wanted to post the TIME he would not have done it this way.

21:30-33 is what he gave us,
21:30:33 would have been a time-marker

The "- " That small line is of importance !

I wish there was someone who could decypher this code-talk
