If so can someone break it down for me I don't know much about Terminal/Mac.
Can you see if and when the file was modified. The time stamps don't add up could be UTC. This is rather important.

The -07:00 is simply the timezone of your computer (or at least, what exiftool thinks it is).
All other date/times are coming directly from the recording device (e.g, camera), they simply depict the time that your camera clock was at.
Does this answer your question?
It was recorded from a cellphone so the time is never really wrong. What do you make of the 3-27 09:01 time? My phone wasn't even on me unless that's 9:01 Pm then maybe.
The time zones in QuickTime-format files are inconsistent. If they are stored as UTC, then you should add "-api QuickTimeUTC" to your command to convert them to local time.

Thanks that seemed to work. But the File Modification Date/Time didn't change, do you know whats up with that? Anyway to see if someone modified it.

The QuickTimeUTC option only affects interpretation of QuickTime date/time tags. Use the -G1 option to see where the information is coming from, and see the QuickTime tags documentation (https://exiftool.org/TagNames/QuickTime.html) for more details about QuickTime tags.
