Totally stumped on this. Copied some mp4 files off my phone, that I need to show a correct date for. Checked the file properties and found an empty "media created" date field. The date should've read 2019/01/22 7:49 pm.
Tried to use exiftool to fix the issue with the command:
"-CreateDate=2019:01:22 19:49:14-05:00" 20190122_194914.mp4
Then my machine spat
2019/01/22 2:49 pm. in my face instead.
I even used the modify all dates command
"-AllDates=2019:01:22 19:49:14-05:00" 20190122_194914.mp4
Same 5 hours behind result. Running the file on exiftool shows the correct dates. I know my system time is correct.
I'm running windows 10. My system time and timezone setting are correct. I haven't had this problem with the photos I copied over. The "Date Taken" value was retained, and changing things through exiftool still gives the correct time in the properties. Any suggestions on how to fix this with .mp4 videos or am I missing something with exiftool?
