I've created a cryptic crossword clue for a short story I'm writing. It starts with the protagonist pondering the clue, the solution for which is "time". This is thematic, as is the fact that he can't work it out.
The clue I came up with is this:
The days were given out in reverse order (4)
"Given out" => "emit", and then you put it "in reverse order" to get "time" (defined by "the days").
I'm not very good at solving cryptic clues, and this is my first time trying to come up with one myself, so I'm turning to the experts.
Does this clue conform to the standard rules of cryptic clues? What can I do to improve it?
