Nanoseconds times on EXT3 always seem to be zero

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On an EXT3 file system, I see the following:

dave@mx3210:~$ touch xyzzy
dave@mx3210:~$ ls --full-time xyzzy
-rw-r--r-- 1 dave dave 0 2008-01-06 15:07:01.000000000 -0500 xyzzy

However, on tmpfs, proc, etc., I see the sub-seconds time.  This is
2.6.22.14 and 2.6.22.15.

The behavior of 32 and 64-bit kernels seems to be the same.

With an old 2.6 x86 kernel (suse), I see sub-second times on a EXT3
file system.
