It may not be unreasonable to assume there are larger % of Americans that are more likely to be ignorant on the matter, but it is unreasonable to assume that's what I meant, or think that's what I meant, let alone say that's what I meant - you think. For all your know, a higher % of American Trek fans are aware of this than the % of non-American Trek fans. We just don't know. Who would even do that study?And I think you mean the 24hour clock still confuses many Americans as adoption of the 24hour clock (to varying degrees) is more widespread outside of the USA.
Regardless, I just said "some people" and I see no good reason to try to further refine which people, since exactly which demographic is entirely of no consequence to the topic. And it's moderately unTrek-like, too, to attempt to further divide people rather than unite them. Ha ha.
