Preheat oven to 300 degrees Fahrenheit. Spray a 9-by-5-by-3 inch loaf pan with nonstick cooking spray and set aside.
In a mixing bowl, mix together flour, baking powder, baking soda, and spices. Set aside.
In a large mixing bowl, whisk together eggs and both sugars for approximately 2 minutes or until mixture is thick.
Add the oil, honey, zests, and coffee to the sugar and egg mixture, and blend well.
Add the dry ingredients to the wet ingredients and blend well using a rubber spatula. Whisk briefly if lumps form.
Pour batter into prepared loaf pan and bake for approximately 1 hour and 22 minutes, or until a small sharp knife inserted into the center comes out clean.
