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

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

Hope this helps,
