Incorrect DateTime in EXIF info (Samsung S9+ Front Camera)

Question

The original file from Samsung S9+ Front Camera has in JPG correct DateTime in a file (EXIF).

All files exported in Lightroom 8.0 from Samsung S9+ Front Camera to JPG has incorrect DateTime because it is a current date + orginal time 😞

Files exported from Rear Camera are OK 😉

I forgot that I had diagnosed the same problem with the S9+ front camera two months ago. You should report this bug to Samsung.

Note that the EXIF field DateTime is defined by the standard to be the date/time that any photo application modified the photo (including creating it) -- it is not necessarily the capture date (when the shutter was pressed). The EXIF field DateTimeOriginal contains the capture date.

When a camera first creates a JPEG, it typically sets DateTime to the same value as DateTimeOriginal. But when LR exports a photo, it sets DateTime to the current time, as specified to the standard.
