Good Afternoon,
I recently discovered my camera's date was one day behind, and messed up some of my recent holiday pictures.
Downloading and working with ExifTool Ver 8.92 and ExifToolGUI Version 5.11, the uncorrected value for the following shows:
-exif:DateTimeOriginal 2012:04:28 11:27:00
-exif:CreateDate 2012:04:28 11:27:00
-exif:ModifyDate 2012:04:29 19:26:00
However, in Windows Explorer (using Windows 7), the columns for :
Date Taken = 28/04/2012 11:27
Date Created = 30/04/2012 02:14
Date Modified = 30/04/2012 01:26
which has me rather confused, as I am 100 % certain the computers date was correct, and also the images was downloaded the same day, the 29 April 2012.
I have managed to correct the date, by adding one day to the pictures affected, using Exif:DateTimeShift with only DateTimeOriginal and CreateDate ticked and Shift Amount set to one day, and Increment ticked.
However - after correcting the day with one, the values in ExifToolGUI Workspace shows:
-exif:DateTimeOriginal 2012:04:29 11:27:00
-exif:CreateDate 2012:04:29 11:27:00
-exif:ModifyDate 2012:04:29 19:26:00
which looks correct.
However (gee - I just hate this word...) loading Windows Explorer up, the columns shows:
Date Taken = 29/04/2012 11:27
Date Created = 30/04/2012 02:14
Date Modified = 30/04/2012 01:26
and only Date Taken have been corrected.
I am at a loss as to why the remaining two columns have not changed, and would really appreciate any information.
Thank you,
So far so good - but when the files are displayed in Windows Explorer (using Windows 7)
I don't know what you mean by EXIF:DateTimeShift, but it is likely that the two date/time values that weren't changed are those stored in the filesystem and not in the image file itself. ExifTool can change the filesystem modification date/time (FileModifyDate), but can not be used to set the filesystem creation date/time.

Hi Phil,
Thank you for your reply - actually, the Exif:DateTimeShift is the option in ExifToolGUI in the menu under Modify > Exif>DateTimeShift.
My apology for the confusion.
I think I have come to the conclusin, that the information in Windows Explorer is somewhat different to the exif-data stored in the images, but had me confused for a while.
Kind regards
Hi,
Phil yes, GUI menu Exif:DateTime shift is a "user friendly" option to shift these three tag values easy.
to nq270:
To keep my explanation short; don't bother much with Dates shown in Windows Explorer. Most of them are "system" dates (when file was created, modified, accessed, etc.). And the only value which seems to deal with Exif dates, is "Date taken" column. You can be 100% sure, that DateTime values given by ExifTool(GUI) are always actual values currently stored in metadata. Meaning: if Date values differ, then Windows is wrong or you are looking at some other (not image metadata) value.
