Passing stuff through DxO PL 5.2.3.66 (latest) Mac OS caused this:
RAW file taken at (example) EXIF says:
DateTimeOriginal : 2022:06:04 16:42:01
CreateDate : 2022:06:04 16:42:01
When exported as DNG or sent to DCU, this happens:
DateTimeOriginal : 2022:06:04 21:42:01
CreateDate : 2022:06:04 16:42:01
DxO is adding 5 hours to the export.
Opened case, sent to DxO.
They responded:
"We have heard back from our development team. They thank you for the file you sent to us, and they can confirm that this issue is due to an incorrect timezone of +00:00 being incorrectly added to exported files. This issue has been fixed recently and will be available in the upcoming PL 5.3 release."
I am not aware if this happens with Windows version, Windows users should check.
I had to fix dates with exiftool "-DateTimeOriginal<CreateDate"
