Package: mount
Version: 2.16.2-0
Severity: important
Tags: l10n squeeze
I have recently done a dist-upgrade from lenny to squeeze. I have noticed that
the file modification times (ls -l) on a mounted VFAT USB disk are offset by
the two-hour difference between my local time (MET-1METDST) and UTC (AFAIK
this was not the case on lenny)
A file that was created on a Windows XP computer at 18:00 local time shows up
with a file time of 20:00.
This situation is not changed by specifiying the mount option tz=UTC, so it
seems that the VFAT partition is by default mounted with timezone set to UTC
(Unfortunately there exists no tz=local mount option)
I am running with the HW clock set to UTC,
and my /etc/default/rcS setting is :
TMPTIME=0
SULOGIN=no
DELAYLOGIN=no
UTC=yes
VERBOSE=no
FSCKFIX=no
RAMRUN=no
RAMLOCK=no
The relevant dmesg output is

This bug seems to be related to Ubuntu Bug #426886
(https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/426886).
Default timezone for VFAT should be local, as any UTC
partitions can be mounted with tz=UTC (it seems UTC is the only tz option
currently accepted, 'local' cannot be enforced)
Changing UTC to 'no' as suggested in some forum posts is IMHO not an option
as running with the HW clock set to UTC is the correct way .
