If yogurt is left in a hot car for 45 minutes before refrigeration, what has effectively happened to its shelf life?

A portion of its calculated shelf life has effectively been used up.

The countdown on shelf life begins the moment the product leaves the manufacturer's controlled environment; exposure to unfavorable conditions like high heat consumes the allotted time before reaching optimal storage.
