Are you thinking like this: "The granularity of the
clock is 1 minute. So it should be updated once every
minute, i.e. every 60 seconds."

That sounds a bit risky to me, so I'd recommend setting
it so that it will be set somewhere around three times
per minute - and not set evenly so, but for example
every 22 seconds:

    0, 22, 44, 6 (66), 28, 50, ...

>>>   (run-at-time nil 60 (lambda ()

>>>   (erase-buffer) (dotimes (spaces (- (frame-width)

In X it works with 5. In the Linux VTs and in xterm
with '-nw' it needs 6.
