It uses the low 4 bits of this field for the seconds, for which values of 0-29 are valid, and are multiplied by 2 to get the final value. The File System Component fully supports time stamping for files and. Technical backgrounder: Basically FAT uses 2 bytes to store the time (hours/minutes/seconds) of the file create in the directory entry. rwxrwxrwx 1 root wheel 305981 Mar 5 13:07 Alien_ Isolation™_20170305120653.

I transferred the file to my memory stick within minutes of having taken the screenshot. Note also that the file name itself contains the correct time when the file was created. # mount_msdosfs -L en_US.UTF-8 /dev/da1s1 /mnt/īut when I list the directory contents, the time stamp of the files is off by one hour into the future compared to actual time when the file was created as shown below.
