Time indicator is shown as "%a %H:%M" in the center of the top bar.
How do I move it back to the right where it belongs, and make it include the full date and time ("%Y-%m-%d %s %H:%M").
This is a regression in 17.10 from 17.04 in the Ubuntu login (Unity seems to work as it did in 17.04).
PS. It is an observed regression because the default login behaves worse than before.
