What's the name of this jazz song?

I heard a jazz song on NPR about a month ago. There was a female vocalist, and in the chorus, she kept repeating 12:59 (or 1:59). I’ve looked on NPR, I’ve looked on YouTube, iTunes, about 15 lyric websites. I even tried those apps that you sing into or hum into, but they couldn’t find it either. At this point, PLEASE DON’T offer suggestions on what else I should try. (I’m too frustrated for that.) I’d like to see if anyone knows the song first. Thanks!
