Did Miscrosoft change how it dates files?

Usually, there is no problem. But tonight, as I go to close up operations for the evening, it is copying far more files than before. all tagged "newer". Was there something magical about the shift to Daylight Savings time which makes a source drive file dated "Jan 2 2019 10:20 AM" to now be "newer" than the target drive file dated "Jan 2 2019 10:20 AM"? If you use the /TS option, robocopy will show you the timestamps of the source file. That it does. Even as it updates all the files on thumbdrive G: from Thumbdrive F: - both FAT32. Meh. Major issue is that, knowing this, I will know to sync thumbdrives earlier in the day, in order to not have to wait a half hour while it updates all the files. Now the question comes to me: what about the files on the external hard drives, which are NTFS? When the source file is on an NTFS drive, that will be in UTC, not your local time. (The timestamps displayed in File Explorer are converted from the NTFS native UTC to your time zone.) Sigh, one more place where the softies have gotten "clever."
