In a large mixing bowl, beat together the butter and sugars.
Add eggs one at a time, beating well after each addition.
Stir in vanilla.
In another, smaller bowl, combine flour, baking soda, salt, and spices.
Add to the creamed mixture and stir well.
Add oats and mix well again.
Cover bowl and chill for at least an hour.
Roll dough into balls and roll the balls in granulated sugar.
Place dough balls 2 inches apart on greased cookie sheet.
Flatten slightly.
Instead of rolling the dough balls in sugar, you can place them on the greased cookie sheet and then dip a fork into the sugar and flatten cookies slightly, running the fork across the tops to release the sugar.
