How did my pictures time-travel to the future?

Thanks, but modifying the date modified is not important to me. My bewilderment was simply concerning why/how they could have a future date.

And as a side note, there is obviously code in Windows for identifying files with future dates as "Sometime in the future." So they actually coded that in there. Truly bizarre. I'd like to know the story behind that one.

The E drive is an internal partition with my data on it. The folder marked "OLD C DRIVE" is simply a folder with my data from a previous install of Win7 that I labeled as such. It never was the actual C drive folder; it never was a partition with a drive letter. I just called it that; as in, "this is data from the old C drive." There is no labelling confusion. It does not need a drive letter. It's just a folder.

And yes, there are thousands of files on that partition that are all included in that library - along with hundreds of jpegs - but none of them registers with a future date. It's only those pics, which actually now have increased to 16 with future dates, doubling the previous total of 8 - without any change on my end. It did it itself.

As far as the scanning goes, I have no way of knowing which were scanned and which were not, as many/most of the pics I received were from family members. But I'm not sure how that matters. I'm no scanning expert, but I can't see how a scanning error of some sort would render a future date, especially considering there are dozens of other pics from the same relative that do not have future dates. So I don't think that's a valid trajectory. But that's just me.

So thank you for your suggestions, but I think we're kind of grasping now and I don't want this to drag on. I'll just leave it as a strange anomaly for now. Thanks.

There are a variety of reasons why a file might have a future date. One possible cause being that the file was handled by a computer with the wrong date set, even if it was only for a short time. Considering that the issue may have occurred many months ago and not necessarily on the computer in question it would be very difficult to determine the cause.

But it shouldn't cause a problem for either Windows or software that uses the file. Most software doesn't even read the modified date and when it does it is usually only for display purposes. Reading the date is an extra step to obtain information most software doesn't care about. Windows explorer reads the date only for display purposes. The date may be important to people but the real date is in any event lost.

Intelligently designed software will not check the date, compare it with the current date, and conclude that something must be terribly wrong if it is in the future. When the CMOS battery in a computer fails the date as known to the computer will be reset to something usually years in the past and most file dates will be in the future. In some case it may be some time before the problem is noticed.
