Preheat oven to 325°.
Place ham on a broiler pan; insert meat thermometer into thickest portion of ham; cover with foil. Bake at 325° for 90 minutes.
Combine chutney and mustard in a small bowl. Remove ham from oven; brush chutney over ham. Bake ham, uncovered, an additional 30 minutes or until thermometer registers 140°. Place ham on a platter; let stand 5 minutes before slicing.
