Google will treat that the photo is taken at 10 AM GMT+7 - equal to 4AM GMT+1. All photo will be treat as they were taken in GMT+7.Įxample, photo taken at 10 AM GMT+1, upload in GMT+7. In this case, if you took photo in GMT+1 and upload in GMT+7. If GPS Coordinates is NOT presented, Google Photos will assume that the photo is taken in uploaded time zone/location (which is determine by your internet connection IP - you can’t just change Windows timezone setting to fool them) Again, I don't know if this is truly a bug with Affinity Photo, but I figure that you would at least like to know that there's a compatibility issue between AP and a major online photo storing application, even if this latter might be the one doing weird stuff. I hope this extra information can be of use. Of course, all of the files have, in the File metadata, "File modification", "File Access" and "File Creation" dates and times with the "+01:00" affix, which is normal as they were all modified over the last few days. Those that did not go through Affinity Photo, and thus were not affected by the above, do not have these lines in the XMP metadata. EDIT: this is the time at which I reprocessed the image. Those that went through Affinity Photo, and thus were affected by the above, have, in the XMP metadata, a "Modify date" and a "Metadata date" with "+01:00" affixed to the end of the data thread. Having just run into this again, I used the ExifTool function built into XnView MP to compare the metadata of files that I readjusted recently (thus during "normal time") and that were, or were not, affected by the above.Īll concerned images were taken during the summer (thus during "daylight savings time"). Thanks for hearing me out, and if anybody else has encountered this, feel free to sound in. but not by Google Photos (this latter resultantly defaulting to the present one)? Pure speculation on my part. Is AP perhaps changing how daylight savings time metadata is written to a form known by Windows and Co. So what's happening exactly here I do not know. I have not tested this phenomenon in any other photo editing software. Should that photo be reprocessed in summer, again only in RawTherapee, then uploaded again to Google Photos, this new version will still have the correct "GMT+01:00 Central European Time" associated with it. For example, a photo taken and initially processed in winter only in RawTherapee (or not processed at all) will, like above, show the correct "GMT+01:00 Central European Time" in the initial upload to Google Photos. I do not encounter this problem for photos that do not pass through AP. HOWEVER, and here's the weird part: This problem does not manifest on my PC (neither in XnView MP (my main photo browsing app) nor in Window Explorer. The same thing happens in the other direction: a photo taken in summer but reworked in winter will be given the "normal time" although it was taken in "daylight savings time". The date and time will not have changed, but the time zone will be changed to "GMT+02:00 Central European Summer Time" (thus, "daylight savings time").Ħ) Get frustrated, because that photo was not taken during daylight savings time, and now you have to fix the time zone and time data in Google Photos. "GMT+01:00 Central European Time" (thus, "normal time") in my case, when you open the Info function of Google Photos.Ĥ) Wait until summer then open one of your winter photos in AP and reprocess it for X reason and resave the image.ĥ) Re-upload the new version to the Google Photos Album above: the photo will be out of place. Everything falls into place nicely and all the photos will show the correct date and time, and the correct time zone, i.e. So, in my camera, when daylight savings time becomes active, I don't change the time in my camera, I just change the daylight savings time function to "Yes" and the camera corrects the time automatically.ġ) Go take pictures in Winter (so no daylight saving time).Ģ) While still in winter, process the pictures in Affinity Photo, or a combination of AP, and, say, some other raw developer (in my case, RawTherapee).ģ) Upload them to a Google Photos Album and organize the Album by "Oldest first". I'll note here too that I have a Nikon camera in which there is a "daylight savings time" function that one activates when it comes around.
