His high time may lead to hard time.

A Long Island DJ has been busted for allegedly recording himself storming the US Capitol last month — and smoking a joint inside the historic rotunda, according to new court papers.

Greg Rubenacker documented his participation in the Jan. 6 siege on Snapchat, where he could be heard yelling, “Holy s–t! This is history! We took the Capitol!” after he and other rioters blitzed the Capitol building, the federal filing on Tuesday alleged.

The Farmingdale resident also allegedly filmed himself vaping from a blue device, as well as puffing on marijuana joint and declaring, “Smoke out the Capitol, baby.”

He recorded others smoking in the Rotunda, as one of them asks “How many joints we have?”

Rubenacker allegedly holds up his joint in the air and responds, “Hell yeah” before taking a drag, the filing said.

He was arrested on misdemeanor charges Tuesday morning by the FBI and will appear in court virtually in the afternoon.

The feds said Rubenacker’s damning Snapchats were ratted out to FBI investigators by someone who’s known him for multiple years and attended school with him.

Rubenacker posted the videos — including one showing the massive pro-Trump crowd near the Washington Monument with the caption, “America is pissed” — under the username “GREG RUBENACKER,” according to court documents.

Attorney information for Rubenacker wasn’t immediately available.

Numerous people have been arrested in connection with the Capitol riots that left five people dead, including a Capitol police officer.
