Presenting Lengths of Time
==========================

First, let's bring in some dependencies:

   >>> from lp.testing import test_tales
   >>> from datetime import timedelta

Exact Duration
--------------

To display the precise length of a duraction, use fmt:exactduration:

   >>> td = timedelta(days=1, hours=2, minutes=3, seconds=4.567)
   >>> test_tales('td/fmt:exactduration', td=td)
   '1 day, 2 hours, 3 minutes, 4.6 seconds'
   >>> td = timedelta(days=1, minutes=3, seconds=4.567)
   >>> test_tales('td/fmt:exactduration', td=td)
   '1 day, 0 hours, 3 minutes, 4.6 seconds'
   >>> td = timedelta(minutes=3, seconds=4.567)
   >>> test_tales('td/fmt:exactduration', td=td)
   '3 minutes, 4.6 seconds'

   >>> td = timedelta(days=1, hours=1, minutes=1, seconds=1)
   >>> test_tales('td/fmt:exactduration', td=td)
   '1 day, 1 hour, 1 minute, 1.0 seconds'
   >>> td = timedelta(days=2, hours=2, minutes=2, seconds=2)
   >>> test_tales('td/fmt:exactduration', td=td)
   '2 days, 2 hours, 2 minutes, 2.0 seconds'

Approximate Duration
--------------------

To get more friendly-to-display duration output, use
fmt:approximateduration:

   >>> td = timedelta(seconds=0)
   >>> test_tales('td/fmt:approximateduration', td=td)
   '1 second'

   >>> td = timedelta(seconds=-1)
   >>> test_tales('td/fmt:approximateduration', td=td)
   '1 second'

   >>> td = timedelta(seconds=1.1)
   >>> test_tales('td/fmt:approximateduration', td=td)
   '1 second'
   >>> td = timedelta(seconds=2.4)
   >>> test_tales('td/fmt:approximateduration', td=td)
   '2 seconds'
   >>> td = timedelta(seconds=3.0)
   >>> test_tales('td/fmt:approximateduration', td=td)
   '3 seconds'

   '4 seconds'
