Hi Paul,
That's extremely interesting what you're saying about "the filesystem
for a piece of hardware... "
So you mean that in the filesystem architecture, there is a part that
is hardware specific. Something different for example for the SD card
driver or the PCMCIA card driver? I thought everything was more or
less abstracted by the combo filesys / fatfs, etc... So it would be at
a lower level then, and in the platform specific part?
I have access to the OAL of my platform, and I'd be more than happy to
have a look there, and fix it if possible, but where exactly?, for the
PCMCIA architecture for example? What are the keywords to search for
in the source?
I can workaround this issue, but now I'd like to get a better
understanding of the problem.
Thanks in advance.
Alex

It's entirely up to the filesystem for a given piece of hardware how times

convenience. That wouldn't occur to me if I were writing the filesystem
driver, but there's no requirement that the filesystem work a certain way.
Since you're stuck with things as they are, you should go everything
possible to assure that the time zone doesn't change between copying a file
where the time has significance to you and using that time to decide if a
copy is needed (or forget the filesytem time entirely and do a CRC, as well
as a time check, to decide if a new file is to be copied).
