From my previous question I am using the following ExifTool command to add Exif Date info to some photo.
exiftool -v "-FileModifyDate>AllDates" *
However, since we went back to GMT from BST, if I try use this on a photo which was taken during BST the Exif Dates are now all out by 1 hour. Photos taken after the switch are fine
e.g. after running ExifTool:
Photo taken BST, modified time of 11:00, Exif DateTimeOriginal is 10:00
Photo taken GMT, modified time of 11:00, Exif DateTimeOriginal is 11:00
Is this expected behaviour? Is there an override switch which will force exiftool to honour the exact modified date/time and ignore timezone differences?
EDIT: I'm using the Windows version of ExifTool
