File Modified Time automatically increases by 2 seconds when copied to USB?
===

Okay, I'm having one of those weird moments trying to get the file modified time of documents in a USB drive. Normally, when a file is copied to a USB drive the file modified time doesn't change. However, when I copy any file to a USB drive, I discover that the File modified time is increased by two. On research however, I discovered other people have encountered this problem online but I have not seen any answer yet whatsoever except for [this article on wikipedia][1] which says something about read and write time for fragmented files increasing on FAT partitions and does not clarify things for me.

I have not been able to verify whether this happens for all files. However, **what I want to know is any official sources of what exactly happens to the modified time when a file is copied to USB drive**. Will it be advisable for me to modify the file modified time in the code myself? *i.e. subtract two seconds*.
