I use a Canon 50D and Aperture and an iPhone5S -- I have all set to Central time zone...but was just in Portugal.  I imported the images from the cards used in the Canon50D and did the change of time just fine [fromAmerican Central to Europe Lisbon] = then I imported and named the iPhone images - but on reviewing the actual images they are off on time == but I am having trouble figuring out how to batch change the images


For instance the iPhone images on import all say 10/29/13  9:10:48 PM CDT  or some such as appropriate


I did a test batch change of images and they ended up as  10/30/13  6:53:46 PM GMT + 00.00  etc


The problem is that I can tell from the content of the images that the time is off = but it's hard for me to figure out how to properly adjust the time == after all, when I have the iPhone with me in Portugal and wifi is working, the time and date are correct and adjust themselves [I have the phone set to pick up the time from the zone I am in]


Any suggestions??

iPhone 5s, Other OS, iOS7

    How did you try to correct the time, Victoria? Don't use "Metadata > Adjust date and time" (unless you already used it - then you need to revert that change), but use "Metadata > Batch change > Adjust Time Zone". The problem is, that when image files do not contain a Time Zone stamp, Aperture will by default use the current system time your mac is set to as the time zone of the images on import. Usually you will set the "Camera Time" and "Actual Time" in the Import panel, to tell Aperzur ethe correct time zones. Only that is not possible, if you are importing images taken in several time zones at the same time.


    You cannot batch change all the time zones of all images at once, if the camera time zones differ - it is really a bit involved. I had similar problems with my camera and iPad, when we were travelling in Aslaska and Canada this summer and were frequently changing the Time Zones - sometimes two times a day. The iPad with automatic time zone setting was very problemitic, because I never could be sure of the time zone on the iPad - if there was no Wi-F,i it would use Canadian Time on Alaska ictures and vica versa.


    • Separate your photos into albums with images that you are sure have been taken with the same camera (iPhone, Canon) and with the same time zone setting in the camera.
    • Then, e.g., select the album with all photos taken on the iPhone, with the Time Zone set on the iPhone to "Portugal" and use Metadata > Batch change > Adjust Time Zone" with the setting "Camera Time is Portugal" (since your camera was set to Portugal, when the photos have been taken)

    To prevent this kind of problem, I always keep all camera times set to UTC. This way I always exactly know the time the camera was set set, when I import the image and do not have to remember to change the time when travelling. Only, that is not feasable with iPhone and iPad. If you want to use your iPhone as a clock and not only as a camera, it is impractical to have it set to UTC.
