I want to know the answer to the following question:
What erroneous date did some users start seeing on their consoles?
All the background I'm provided with is that "However, the root cause of the problem was unrelated to the PlayStation Network, since even users who had never been online also had problems playing installed offline games (which queried the system timer as part of startup) and using system themes.". Is that enough to answer the question?
Answer: no
