FAT timestamps have a granularity of 1 second,
Not quite.
Last modified time is recorded to within two seconds (FAT squeezes the
seconds into a 5-bit field, which allows packing a time into two bytes).
Other times are recorded with different granularity, sometimes
depending on the OS/version used to make the change to the file
system.
And of course FAT has no concept of time zones; everything is local
time, all the time.
https://en.wikipedia.org/wiki/Design_of_the_FAT_file_system#Directory_entry
has some of the gory details.
