In the suburban western part of the U.S. that I'm familiar with, banks will often have a sign out by the road that gives the current time and temperature, and maybe the date. Do they do that in places like New York? I'm having a hard time picturing the same thing in an area that's mostly skyscrapers.

I want a character to be walking around in Metropolis and see something that tells them definitively what the date is. I thought of having them come across a newspaper in a trash can, but there's no guarantee that the newspaper would be today's.

"It is a remarkable dichotomy. In many ways, Clark is the most human of us all. Then...he shoots fire from the skies, and it is difficult not to think of him as a god. And how fortunate we all are that it does not occur to him." -Batman (in Superman/Batman #3 by Jeph Loeb)
