"""``Timer`` displays the elapsed time since the bar started.

Reach for it whenever "how long has this taken so far" matters more

than an estimate of what remains -- unlike the ``ETA`` family, it needs

no ``max_value`` and works just as well for indeterminate work. Compare

``CurrentTime`` for the wall-clock time of day instead of a duration.

This example runs longer than most in this set: elapsed time is only shown

to whole-second resolution, so a bar that finishes in a few milliseconds

would read "Elapsed Time: 0:00:00" for its entire run -- the one thing this

widget exists to show would never move.
