Correction, path should be System Preferences ➙ System ➙ Date & Time ➙ Date & Time (Tab) ➙ Open Language and Text… (Button) ➙ Formats (Tab)
THANKS. That seems to be related. My language (under the Language tab on this window) was set to English, but the Format (tab) should have said United States, but instead said Custom. Changing it to United States showed a change on that window where they display examples of the Jan 1 date.
Interestingly, only the abbreviated date was wrong. The others showed 2011, except for the one marked as Jan 1, 2000.

So I clicked the "Customize" button and it showed that once choice (of how to display it) as a typed-in value (vs a menu choice) and it had been typed in "2000"

So, now I have it corrected to United States, not Custom, and all the example formats are 2011 (as they should be). The days of downloaded files have all changed back to proper year, so apparently the dates were saved right, but display (and sort) wrong.
Thanks for your insight.
As far as the iPhoto Events having the wrong Dates, my conclusion is that this "Customized" date format glitch is the culprit: Since the individual photos each have the correct date despite the Event having the wrong date, I have to look at the Event date as merely a wrong name, not a reflection of a wrong date.
Since I gave a test import no name prior to import, just now, it named the import/Event with the Abbreviated date (which is now correctly formatted). That name should "ride with" the Event regardless of what else I do to the photos. It's just a name that gets assigned which happens to look like a Date (I could name it a date in the future and it would have no bearing on sorting or other data functions).
Thanks!
