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. format controls the text (default Elapsed Time: %(elapsed)s) and the readout has whole-second resolution.

• :doc:`eta`: a remaining-time estimate, which does need a known max_value.
• :doc:`current-time`: the time of day instead of a duration.
