That's one interpretation. Another interpretation might be a 24-hour period of time, which might be a more reasonable interpretation. You have high-priced lawyers and presumably they're right. I'm just thinking off the top of my head and haven't taken the detailed analysis that you have, of course, but certainly one solution would be that you just defer the publication of the ad.
Why couldn't you defer the publication in order to have a 24-hour or 48-hour waiting period until you first publish it? Then it would be quite easy to do, wouldn't it?
