A deranged man walked up to a stranger on a Manhattan subway platform early Wednesday morning and asked for the time before slugging the man in the face, cops said. 

Christopher Lisojo, 31, approached the 29-year-old victim on the C and E train platform at the 50th Street and Eighth Avenue station in Midtown at around 3:50 a.m., according to police.

Lisojo asked him for the time before socking the man in the nose.

Lisojo stayed on the platform – and the victim approached NYPD cops at the station and gave them a description of the pugilist. 

Police tried to arrest Lisojo, but he resisted by flailing his arms to avoid being cuffed. 

He was ultimately arrested and charged with resisting arrest, assault and criminal possession of a controlled substance, police said. 

A crack pipe was found in his pocket, cops said.
