1. A timing device comprising:
- a. a first timing component for indicating a first time period; and
b. a second timing component for indicating a second time period comprising a time that the timing device has been exposed to a predefined temperature during the first time period,wherein the second timing component is automatically activated upon reaching the predefined temperature during the first time period.

Abstract
A timing device that includes an anode layer, a cathode layer and an electrolyte attached to a base layer. The anode layer and the cathode layer are placed adjacent to one another along an axis of the timing device. Upon activation of the timing device the anode layer is depleted away from the cathode layer until the timing device is fully expired. Once the timing device is expired, a change is seen indicating that the timing device has expired. In some embodiments, a color change indicates that the timing device has expired. In some embodiments, as the timing device expires electronically readable information is uncovered.
