Try taking a video and import it into LR Classic CC. I have proof from my phone when I took and what it shows on the camera then it being different in LR. From my iPhone. Shows bottom left 2019-09-23 6:13pm which is the correct time.
After Importing it, on the right even the filename is wrong. My settings import is both Date and Time. So it's wrong in the Filename AND in the Metadata Date, and the Date Time Digitized
As you can see in my filename is should be 20190923_001813
I have a very similar issue with my Sony A99M2 and A77M2 cameras. Typically I will import the video (usually MP4) into Sony's Playmemories Home Browser aka PMB so I can edit before finally importing into LR CLASSIC. By doing this PMB will give the MP4 a modd sidecar file. Unfortunately, apparently LRC doesn't read the modd side car files. Will Adobe ever allow LRC to read the modd files and either convert to LRC sidecars or at least give option to write metadata from disk?
The camera recorded the capture time as 2019-09-23 18:13, while LR read the capture time as 2019-09-24 00:13:02, a difference of 6 hours. Are you in a time zone that is UTC - 6 (e.g. MDT)? If so, this issue is most likely caused by the poorly written QuickTime spec, which doesn't provide a standard mechanism for cameras to record time zones in the metadata. See here for details:
You could post your camera and request that LR handle it specially, as it does with a few of the most popular phones and cameras.
This is primarily a user-to-user forum and Adobe won't see your feedback here, so be sure to post on the bug report I linked to previously. Adobe does read everything posted there and sometimes engages.
This has been a known issue for probably a decade now and extremely maddening. Adobe clearly has no plans to fix it and it's on their list of known issues for lightroom. https://helpx.adobe.com/lightroom-cc/kb/known-issues.html
A possible workaround: Change the time zone in the camera settings to UTC. The camera will then record capture times without adding a time-zone offset, and LR will read those times as recorded (interpreting them as local time),
