Time shifted by 2 hours after import of videos

I use a Nikon 7100 for both photo and video and I import both into Photos for Mac (Version 2.0 (3161.4.140)). So far so good. Import works fine for both, but after the import the "timestamp" (time taken) in the video is shifted by +2 hours. The "timestamp" in the photos are OK. So I need to remember to "adjust time" by -2 hours after every import of videos. A bit annoying. I should say that the time recorded by Nikon on the SD cards are OK. Any suggestions to what might cause this? An bug in Photos maybe?
