Abstract

Apparatus and associated methods relate to a timer having multiple time resolutions corresponding to multiple environmental climates. Climates may include, for example, temperature, humidity, pressure, or any of these taken alone or in combination. Climates may include, for example, carbon monoxide content, oxygen content, toxic gases, or any of these taken alone or in combination. The resolutions and climates may be particular to selected applications, including but not limited to, perishable foods, chemicals (e.g. alcohol, cement, pharmaceuticals), or perishable evidence (e.g. crime scene materials). In one embodiment, a breast-milk timer may have three times scales, an hourly scale corresponding to room-temperature environment, a daily scale corresponding to refrigeration, and a monthly scale corresponding to a freezer environment. As time elapses, the timer may automatically transition from the hourly scale to the daily scale and then to the monthly scale. Such a timer may quickly communicate breast milk freshness.
