A little more than that ... Some versions of Windows apparently already display the EXIF date/time for JPEgs - something that caused me a certain amount of confusion when I couldn't understand why a piece of my code (which used the timestamp stored in the filesystem) showed different details for two copies of a file even though folder display on my Windows system showed them as the same date/time (the timestamps differed by an hour because of a bug in the way certain versions of Windows apply DST to file timestamps when they're copying files, but that's a whole different can of worms). Setting the actual timestamp stored in the file system to match the EXIF date/time means, in theory, that your file system information now matches what was (or should have been ...) associated with the file when your camera initially created the image. But unfortunately it's a whole lot more complicated than that. There are generally at least two timestamps associated with a file - one showing the time the file was created, and one showing the time the contents were last modified. These start off the same, but they don't always stay that way. And, very confusingly, when you make a copy of a file, the way the timestamps on the new copy get set can be different depending on what software you are using . . . -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
