Miss Him, Miss Him, Miss Him (Time & Temp)

Browne Chronometric Engineering, Inc. has a straightforward mission statement:

To police and protect the historical integrity of the temporal order against all anomalies, anachronisms, and other threats.

That means that when World War 3 suddenly seemed to have occurred in 1970, someone needs to figure out why and fix it -- fast. That's you, low paid temporary workers from throughout history. Whether you're a slope-browed caveman or a rejected space-jockey from the 23rd century, you're picking up a little extra cash at BCE as a cubicle drone while you're between jobs. Time for you to go earn your minimum wage. You're headed back to a Time almost 20 years after the bombs stopped falling to find out what happened from the survivors. But a lot has changed ... from geography, politics and economics to music, shopping, and computers. What is cause, what is effect, and when do you get your mandated coffee break?
