Preheat oven to 400º.
Combine the first 3 ingredients in a small microwave-safe bowl. Microwave at HIGH 4 minutes.
Heat oil in a medium saucepan over medium heat. Add onion and garlic; cook 5 minutes or until tender, stirring frequently. Add apricot mixture; cook 10 minutes or until apricots are soft. Stir in honey and thyme. Place mixture in a food processor; process until smooth, scraping sides. Reserve 1/2 cup apricot mixture to serve with pork.

Reduce oven temperature to 350º (do not remove pork from oven). Bake 1 hour or until thermometer registers 155º, brushing with 1/2 cup apricot mixture after 30 minutes. Let stand 10 minutes before slicing. Serve with reserved 1/2 cup apricot mixture.
