Combine oats, butter, cinnamon and 1/4 teaspoon nutmeg in a small bowl. Press mixture onto bottom and up sides of a 9" round pie plate.
Bake at 425 degrees for 7 to 10 minutes, until lightly browned.
Meanwhile, combine cottage cheese, cream cheese, eggs, dates, 1/3 cup of the pineapple juice, vanilla extract, orange zest and remaining nutmeg in a food processor, mixer or blender and mix well.
Pour into cooled crust and bake at 350 degrees for 30 to 35 minutes until filling is set, then chill at least one hour.
Combine remaining pineapple juice and cornstarch in a small saucepan and heat to boiling, then boil 1 minute, stirring constantly, until thickened and clear. Arrange drained apricot halves on top of cheese filling and spoon pineapple glaze evenly over apricots.
