Wrong DateTimeOriginal metadata in DNG from OnePlus Nord

[shyrodgau]

I use FreeDcam from FDroid on a lineageos One+ Nord and take JPEG+DNG per each exposure. On some DNG images, the DateTimeOriginal is wrong (most likely the DateTimeOriginal from another picture taken while the program was open). The Tag in the JPEG is correct.

To Reproduce
Take several photos without closing the app when JPEG+DNG is configured.

Expected behavior
The DateTimeOriginal in DNG should be the same correct one as in the corresponding JPEG.
