Ladies I need some help please!

I do a lot of posting on BP and I have a question about the automatic posting.
I have never done it before, but i see that it saves money to do it the automatic posting way...
It says on the slot where you pick the time:
"Automatically re-post your ad to the top of the listings every: 1 day after 6pm"...
it lets you change the time and everything.. but does that word "after" mean it doesnt post right at the time you choose?
Because I would like it to be at the same times every day, not whenever it decides to do it...
Sorry if I sound stupid, just dont want to waste my money if it isn't what I want.

I posted this in the females room too, but was not really sure what category this post belonged in. Sorry! lol
