Show X hrs after published time

Hello,
I wish to show a section of a post 24hrs after the publishing time but the publishing time will vary as the post is submitted by a third party provider.

What I think I need in the settings would be a shortcode which I can wrap part of the post in to show 24 hrs after recorded published date/time (I can do this wrapping via sections of the post submission form without involving the third party).

Looking in your settings it’s all specific dates/times, not show or hide this x hrs since recorded published time/date?

Is this possible?
Thank you
