I think you may be downvoted (wasn't me either) because you assumed a negative consequence and negative reason without even trying to think of positive ones. I would assume that they don't reprint or reshoot things, they just have a style guide so all affected people know to set the time right. As I wondered in my other comment, maybe they have tools to help them do this. And if there is a mistake (somebody forgot to set the right time), they probably fix it in photoshop. As to why this is done, I think a company that displays so many interfaces containing a clock of some sorts, and that is known for attention to detail might try to remove any possible negative view of their ads. We often rely on the devices they sell to tell the time, so our eyes are naturally drawn to the time display in ads. If it were something odd like 3:33am or 11:12pm that might make the viewer wonder why, and get distracted from the message of the ad. I also think that 9:41am is a positive time. It's when most people are alert and productive, feeling like they have a whole day ahead of them. I would not overlook such touchy-feely effects in advertising.
