Military Time

Sometimes in my books the time used is Military Time.  Instead of two twelve hour sets of numbers the numbers go from 0000 - 2400.  Because the military has to work on a 24 hour schedule it makes sense to use 24 hours instead of 12 twice.  No one gets confused as to day or night hours.

So in the book, A Light Shines Forth, when Stephanie leaves a note for Noah to meet her for root beer in the middle of the afternoon can you guess what time she writes on the note?
