Published times and flight times are never the same.
They add in buffer for loading, push back, departure, arrival gates, weather, connecting equipment, change in actual air routing, etc.
Impacts on both arrival and departing airports.
If you want to dig in a bit, go to flightaware.com and see what sort of actual times this flight has been tracking.
