In this future the effects of technological failures will be spotty, where one failure will not cause others. People will devise work-arounds for the problems that do occur, and there will be little urgency to the situation. Groceries and gasoline become scarce, transportation of goods and people becomes almost impossible, financial systems stop working, markets crash. The government can't collect taxes, deliver the mail, or defend the coasts. The health care system collapses.
Cities fall into ruin, suburbs become battlegrounds.
Organizations that do not now rely upon sophisticated interconnected systems - gangs, third world countries, etc. Everyday life becomes a nightmare. For example, a one-day shutdown of a single bank might cause many people to withdraw money from many banks at once. Or a temporary gas shortage will trigger gas lines and resulting shortages. Such systems failures are not directly date-glitch related.
