GPSTimeStamp shows 00:00

[restante]

Hi,
thank you for what you have done, it is very helpful.
I only have an issue and I hope you can help with it.

I am adding GPS location (from CGLocation) and creation date to an image, and the container shows as following during debug:

po container.exifData
{
"{Exif}" = {
"2017:09:17 19:44:50" = DateTimeOriginal;
};
"{GPS}" = {
Altitude = "19.23933";
DOP = 65;
Latitude = "51.55607";
LatitudeRef = N;
Longitude = "0.2521907";
LongitudeRef = E;
TimeStamp = "2018:01:11 12:29:26";
};
}
Picture is saved and GPS data is there.
Anyway, using any exif tool, both datetime original and GPS Timestamp are not present

Any ideas, please?

So I do know that there is the following keys "GPSDateTime" (which is the format you indicate here:
"2018:01:11 12:29:26"

But there is also "GPSTimeStamp" which only shows the time which is what it looks like you are inserting in that GPSTimeStamp field 2nd up from bottom within your image... HH:mm:ss

and also "GPSDateStamp" which is another tag altogether... so I am wondering are you using the tag you intended to use?
