Im having a similar problem, but can fix mine with adding hours. Hope an update will fix it!
Looking more closely, it does seem to line up with UTC vs my local time zone, so exactly 4 hours or 5 hours depending on whether it's daylight savings time. Thanks for confirming that it isn't just me, Lars!
I am having this problem too. Sorting by capture time separates stills from video by some number of hours, possibly depending on time zone. This has been going on for months as discussed in the forums. Camera captures and windows shows the correct time. What's with Lightroom manipulating the time. I have Sony. Others have Canon, etc. Capture time is a simple concept. Lets get this fixed.
