Not many questions answered 
What is the actual modified xxxx ? Is earlier / now / ahead-of the computer date ?
Is the computer date correct ? (In days gone by a computer CMOS battery might die and suddenly you found yourself transported back to 1970.)
Gimp does not change dates in-its-self, it will use as a modified date whatever the computer is using.
There are some rules to note:
Transfer / Move / Windows shift-and-drag will keep an existing modified date.
Copy / Windows ctrl-drag files sets the modified date to the computer time.
You will get your unknown back to computer time when you Save-As / Export-As the files even if you have not edited then. That is the same as creating a new file.
A little animation of that https://i.imgur.com/fTJ5r95.mp4 Four files, just opened and the Exported-As with the same name. Modified is back to computer time.
Just a guess, but if you transferred the files from cloud storage, which is probably on a linux server, the file timestamps could be non-compatible with Windows file system. Who knows.
