General Software Discussion / Re: Rotating JPEGs *without* changing modified date
« Last post by tomos on January 20, 2008, 10:57 AM »I haven't yet tested this, but I think that if you backup your photos to a CD or RAR archive in the Winter and erase them from your hard disk, then copy them again to the disk in the Summer, Windows will set the modified time equal to what it was in the Winter (which is the modified time when the files were backed up).
If you leave those files in the disk until the next hour change, Windows will then reduce the modified time by one hour.
Once again, I have no idea if this is the correct explanation for this problem, all I know is that I have a lot of pics with disagreeing dates even though I never modified them.-Cynic (January 20, 2008, 10:30 AM)
