[SOLVED] Fat32 time issue

chh_2009 · 05-20-2011, 01:17 PM

I was created one folder in linux with current time was 1978(For example). I was moved this folder to usb(FAT32 file format).While seeing this folder in window its not showing the folder time created time stamp, because the USB file system only support the year after 1980 .
But again i am putting the same folder in linux ,its showing the correct time stamp. How is it possible?
Because FAT32 only supports timestamp after 1980, but still its showing 1978 in linux system

Welcome to LinuxQuestions.
I think it is just the difference between linux, windows and the FAT32 time stamp.

The timestamp is stored as a number of seconds since a certain date. The interpretation of thidsnumber is up to the OS.

It's, by the way, new to me that FAT32 is based on 1980. Do you have a reference?

It may not be displayed in the windows file manager but it is displayed in the the cmd box if you look at the files via the dir command. The date is displayed as 1/1/1980. I actually created a file via linux as 1/1/1902. After plugging it into the windows computer the date displayed was 1980 and then plugging back into the linux PC it was 12/31/1979. The difference between windows and linux and the vfat module.
