Hmm, well the iPhone (the LR Mobile capture device) sets its own time, and it seems to pick the right time zone. The other camera is a Sony A7ii, which I have set on the correct time. The issue that is coming up is from photos I took on holiday - a two hour time difference from my home zone. The iPhone changed itself, and of course the camera did now. However, LR is still placing an image from the camera after the image from the iPhone, even though the phone image was taken 5 hours later. Even with the two hour time zone difference, it would still be 3 hours different on the recorded time.
