I have never seen the Vantage emit a bad date. What does happen is either 1. The computer lacks a clock, so it synchronizes the Vantage to the wrong time. There is a check in WeeWX to avoid starting up with a clock that's really off, but the best protection is to install a real-time clock in the computer.
2. The logger memory gets corrupted. This is pretty rare, but seems to be triggered by power outages (although not always). The symptom is that WeeWX fails to download any new data, so your webpage doesn't change. See the Wiki article *Wiki generates HTML pages, but does not update them <https://github.com/weewx/weewx/wiki/Troubleshooting-the-Davis-Vantage-station#weewx-generates-html-pages-but-it-does-not-update-them>* for details. This sounds the closest to the situation you describe, but with WeeWX it does not result in a record being downloaded with a bad date. Perhaps wview does something different in this situation. The problem can always be solved by clearing the logger memory. If you do a memory dump first, it does not result in loss of data. Hope that answers your question.
