I think one can afford to be a bit more generous with
updates than once every minute, so it will be (more)
in synch with the system time.

I need to subtract 6 for it to fit. (The time string
itself is five chars.)

Possibly, Instead of the `dotimes' loop, examine if
`make-string' is more efficient, e.g.:

    (make-string 10 ? ) ; 10 spaces
