After the initial technical, the puck ended up in Vegas' defense zone and a play from there was controlled in the middle zone via the skate on Samuel Girard and released William Karlsson.
The Swede lifted a backhand to 1-0 and great cheers erupted among the fans who had barely had time to settle down in the T-Mobile Arena at the classic The Strip in Las Vegas.
The goal is the fastest in the club's short history.
It is noteworthy, however, that they did not join the league until 2017-2018.
William Karlsson also had the previous record when he scored after 14 seconds against San Jose in November 2018.
It ended in a 5-2 victory for Vegas who took their tenth straight victory, also the club record.
They top the entire NHL this season and are already ready for the playoffs.
In Colorado, Nathan MacKinnon was noted for an assist and extended his scoring streak to 15 straight games (nine goals and 17 assists).
It's the longest scoring streak in the NHL this season.
