It means round-the-clock as in "it works during the day and night", rather than literally non-stop. For example, if I said that security did "round the clock patrols", you wouldn't assume they patrol every second of they day, but rather regularly through the night.

The fact a few people might misinterpret it is a marketing bonus, but surely negligable, because no one could believe that.

No, that's exactly what I'd assume. That's how it's defined (MW):

> being in effect, continuing, or lasting 24 hours a day : CONSTANT

I'd expect that they have a rotation of maybe 12 people patrolling for 2h and then switching, so someone is patrolling at every minute.
