When you call the mount helper with `mount -t gluster ...`, all it does is
essentially run the glusterfs binary with the relevant arguments.
i.e.  *mount -t glusterfs -o $OPTION $HOST:$VOLNAME /path/to/fuse_mount *
is the same as manually running:  */bin/glusterfs --process-name fuse
--volfile-server=$HOST --volfile-id=$VOLNAME --$OPTION /path/to/fuse_mount/*

The following fix should expose the --localtime-logging OPTION to the mount
helper:

I'll send a PR after testing. In the meantime, you can try mounting using
eg:
/path/to/bin/glusterfs --process-name fuse --volfile-server=$HOST
--volfile-id=$VOLNAME --localtime-logging /path/to/fuse_mount/ .

Hope this helps,
Ravi

Dear Ravi,

Ah! So it is implemented, just forgot the mount option. Great. I mounted
the volume manually for now as you suggested:

# glusterfs --process-name fuse --volfile-server=gluster03
--volfile-id=homes --localtime-logging /home

And the log in /var/log/glusterfs/home.log is in local time now. Thanks!

Looking forward to your trivial patch getting merged soon...
