As the clocks went back, Manchester City took a step forward by outclassing Manchester United to keep pace at the top of the Premier League table.
Erling Haaland's goal was enough to win the 191st Manchester derby but the brutal truth in the city is that this is just another three points for the Blues in their wider ambitions of winning the biggest prizes on offer.
Having been underdogs for decades in this fixture, the swing to City has been so quick and so hard that the few years when the teams were competing against each other for silverware a decade ago seem much further back in time.
United seem stuck there, as evidenced by Jonny Evans lining up at centre-back against City at Old Trafford for the first time since the 6-1 in 2011 in the season that brought City their first Premier League title.
