My pressure cooker cookbook says times are related to what type recipe you're cooking. Some call for steaming for a short while before putting the pressure gauge on.
Hope this helps.

Date Nut Bread

1-1/4 cups all-purpose flour
1/2 cup coarsely chopped walnuts
1/3 cup sugar
1 tablespoon baking powder
1/4 teaspoon salt
2/3 cup chopped dates
1 egg
2/3 cup water
1/4 cup mayonnaise
1 teaspoon vanilla
3 cups hot water

Danish or other cream cheese

Mix flour, walnuts, sugar, baking powder, and salt. Stir in dates. Beat egg, 2/3 cup of water, mayonnaise, and vanilla until smooth. Add to flour mixture. Stir just until moistened. Pour into greased 1-quart casserole or soufflé dish that fits loosely in 6-quart pressure cooker. Cover casserole securely with aluminum foil. Place cooking rack and 3 cups water in pressure cooker. Place casserole on rack. Close cover securely. Place pressure regular on vent pipe. COOK 40 MINUTES, at 15 pounds pressure. Let pressure drop of its own accord. Remove bread and let cool in casserole on wire rack. Remove bread from casserole. Refrigerate until chilled. Cut into thin slices. Serve with cheese. Makes 1 loaf.
