DST once referred to as "War Time"
https://www.defense.gov/explore/story/Article/1779177/daylight-saving-time-once-known-as-war-time/
It wasn’t until World War II began that the issue came up again. In February 1942, Congress implemented a law instating a national daylight saving time to help conserve fuel and "promote national security and defense," which is why it was nicknamed "war time." The time zones were even known as that: Eastern War Time, Pacific War Time, etc.

Imagine a world where wireless devices are as small as a grain of salt. These miniaturized devices have sensors, cameras and communication mechanisms to transmit the data they collect back to a base in order to process. Today, you no longer have to imagine it: microelectromechanical systems (MEMS), often called motes, are real and they very well could be coming to a neighborhood near you. Whether this fact excites or strikes fear in you it’s good to know what it’s all about.

Privacy concerns:
Many that have reservations about the real-world implications of smart dust are concerned about privacy issues. Since smart dust devices are miniature sensors they can record anything that they are programmed to record. Since they are so small, they are difficult to detect. Your imagination can run wild regarding the negative privacy implications when smart dust falls into the wrong hands.
