These lines did work until...

DateSeparator := ':';
ShortDateFormat :='YYYY:MM:DD';
ImageEnV1 := TImageEnView.Create(Self);
...
Exif_DateTimeOriginal := DateTimetoStr(Date);//'2010:01:01 01:01:00';
EX := ImageEnV1.io.InjectJpegEXIF(BilledNavn);
The result is:
DateTimeOriginal: Saturday, 30. December, 1899 * 12:00:00 AM
DateTimeDigitized: Tuesday, 21. August, 2012 * 12:30:36 PM
Not a correction af 6 hours back. EX is true.
I use it for correction of wrong cameratime.
Why?
Regards
Peter

Hi Peter

Rather than use that date method can you try:

EXIF_DateTimeOriginal := DateTimeToEXIFDate(StrToDateTime(value));

DateTimeToEXIFDate() is defined in iexEXIFRoutines.pas

Hi Peter

Please display the value of EXIF_DateTimeOriginal after setting it and after loading it, i.e.:

EXIF_DateTimeOriginal := DateTimeToEXIFDate(NewDate);
ShowMessage(EXIF_DateTimeOriginal);
EX := ImageEnV1.io.InjectJpegEXIF(BilledNavn);

Load the image again using your normal method then call:
ShowMessage(EXIF_DateTimeOriginal);


What are the values at these points?

Note: DateTimeToEXIFDate() is no longer required.

Just use:

EXIF_DateTimeOriginal2 := value;
