Is "adventure" perceived as a children's and YA genre?

For the past couple years, I’ve been calling my WIP a time-travel suspense novel. But recently, as I prepare to launch it and am working on the marketing strategy, I think the story feels more like an “historical adventure” than “suspense.” I’m also trying to downplay the time travel aspect since @Jonathan Shuerger suggested that portrays my story as more sci-fi than it actually is.

But is “adventure” perceived as a children’s and YA genre? What do you think? I’m doing research on Publisher Rocket but want to hear from readers like you.
