I'm sorry if this subject has been discussed before, but I'm new here 
and the search engine hasn't helped me.

As I was rereading the final chapters of OoP, a question crossed my 
mind. After checking whether Sirius was OK, how long did it take 
Snape to realise that Harry and the others had gone to the MoM?

I can't help thinking that if Snape had warned the members of the 
Order sooner, the outcome of the battle could have been different.
