The mtimes of the files on a VFAT file system on a memory card used by a digicam are off by two hours. My time zone is CEST, which is two hours ahead of UTC so I thought that mounting the file system with -o tz=UTC might fix that.
It doesn't. In fact, in makes no difference whatsoever. Apparently, mount(8) likes to mount VFAT file systems as if tz=UTC were there, even in the absence of any tz= in /etc/fstab or on the command line. Am I alone in seeing this ? A similar bug was already reported in 2010 and closed in 2013 because the maintainer couldn't reproduce it : https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=577597 -- André Majorel <http://www.teaser.fr/~amajorel/> bugs.debian.org, the spammers' favourite.
