creation date - modify date don't match
« on: June 17, 2020, 12:31:47 PM »
Hello,

When analyzing a video from from an iPhone 8, I see this gap in time.  Can I get an explanation as to why this might happen when using ExifTool to analyze?

Media Modify Date : 2020:01:08 22:25:16
Creation Date :        2020:01:08 17:22:11-05:00

 :-\

I can't explain difference in the minutes/seconds, that would be something to do with the camera.  But the difference in hours is equal to the time zone.  See the fourth paragraph on the Quicktime Tags page
   According to the specification, integer-format QuickTime date/time tags should be stored as UTC.
Troubleshooting hints:
* When posting, include your OS, Exiftool version, and type of file you're processing (MP4, JPG, etc).
* Double all percent signs (%) in a Windows batch file.
* If your GPS coords are negative, make sure and set the GpsLatitudeRef and GpsLongitudeRef tags correctly.
