That behaviour seems to have changed now. The Picasa API now returns a different timestamp for the same photo than some time ago. The timestamp that is returned now seems to be valid for the timezone that matches the geotag of the photo. Unfortunately it does not seem to be possible to ask the API what timezone it has used for calculating the timestamp. So one has to perform the same coordinate-to-timezone conversion as the API to know how to convert the timestamp back into a date. Only to finally obtain the plain date that is already stored in the photo file. It seems to me that the idea of converting the timezone-independent plain date stored in the exif data into a timestamp was a bad idea from the start. The change described above now repairs some of the defects for the price of additional complications. When I look at a picture taken in New Zealand, would I ever be interested in what time it was in Germany at that moment?
