Looking for a way to bypass time difference when xcopying

I have several batch files that keep the data on my computers synchronized. I also use them to make backups to USB.
I made the mistake of restoring data from a backup on a USB flash drive, and now there is a time difference for the files from the USB drive, where they are slightly newer.
So, after restoring from the USB, synchronizing - via xcopy /s /d /y - goes wrong in that it considers all files newer.

Is there a way to bypass this or should I update all batch files to use robocopy instead?

How much difference is "slightly newer"? How is the USB drive formatted? NTFS? ExFAT? FAT32?

The RoboCopy /FFT option to round to the nearest 2 seconds may be helpful, depending on how much difference we're talking about.

The time difference varies from file to file. On some it's one second, but I've also found some with a difference of up to 8 seconds.
It's a flash drive, so Fat32.

Thanks.

My experience over the years is that copying folders will change the date and time, Windows File Explorer first creates a new folder which gets the current date and time in the destination then copies files into that folder with the files retaining their date/time of creation. If wanting to change any of the Attributes such as date or name I use one of the usually-free file managers such as FreeCommander, MultiCommander, etc., that I download from MajorGeeks. And some will be Portable, can use on a USB Thumb drive without actually installing, just download a .zip file and decompress into a folder.

Thanks, all.
I'll switch to robocopy.
I'm already using for some batch files.
