#------------------------------------------------------------------------
# test input
#
# NOTE: these tests check that the Date plugin is behaving as expected
# but don't attempt to validate that the output returned from strftime()
# is semantically correct.  It's a closed loop (aka "vicious circle" :-)
# in which we compare what date.format() returns to what we get by 
# calling strftime() directly.  Despite this, we can rest assured that
# the plugin is correctly parsing the various parameters and passing 
# them to strftime() as expected.
