File has no 'Date Modified'

[Terry Pinnell]

In a My Computer folder of 20 or so JPG files, one has no entry in the
Date Modified column. Don't recall ever seeing that before. Remains
the same if I move it elsewhere. Any ideas how that might arise
please?

Date Accessed and Date Created are both present if I choose to display
them.

I've just examined the file, Point01.jpg, in IrfanView with
Image>Information, and its File date/time field says:
08/07/28980 / 18:42:35 Just a bit ahead of itself there!

Point02.jpg for example has 24/01/2006 / 15:50:55
which was when I created all 20 of these files by screen capture from
a map program and then cropped in IrfanView.
