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. -- Michael Kjörling • https://michael.kjorling.se • michael@kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
