Ah, so it is a "religious" thing (FAT32 vs NTFS).

FAT32 is irrelevant here. The 2 seconds time unit is a legacy of FAT12. So,
it's been there for a long time. FAT32 can not be a new file system format
because it needs some backward compatibilities with FAT16 and FAT12.

Now to see if I want to go to the hassle of changing thumbdrive
formats.

If you're considering it, for portable drives, consider exFAT instead of
NTFS. While you can use NTFS for portable drives, extra care must be taken.
Otherwise, you'll have higher probability of loosing some of your data.

FYI, exFAT has a 10 milliseconds resolution for file dates. NTFS has 100
nanoseconds.
