File's time on Linux and Windows

Description of problem:
The time of files FAT formatted devices (hard disk partition, USB key or SD cards ...) are not correct after DST (Daylight Saving Time). For example:
1) before DST, in summer time (21th of August) at 15:36, I saved a file "15h36.txt" on an USB stick
2) after DST, in winter time (6th of November) at 10:26, I saved another file "10h26.txt" on the USB stick

Results:
- On Windows => everthing is OK concerning the dates, before and after DST (see attachment)
- Idem with "DIR" MSDOS command
- On Linux => before DST, the time of the single file "15h36.txt" was correct
- On Linux => after DST, the time of the new file "10h26.txt" is correct BUT the time of the old file "15h36.txt" is now erroneous !! There is one hour shift ! (see Attachement, made with dolphin, but it is the same with other methods, like "ls" command)


How reproducible:
Always

  
Actual results:
There is a one-hour shift for files after DST => it is not possible to have every files at the correct time: if the ones after DST are correct, the ones before are not (and vice versa)

Expected results:
Every files should have the correct time displayed !
- This is the case in Windows (see attachement) and MSDOS
- This is the case in Linux for the other FS (EXT2/3, NTFS)
