# Code to put a due date countdown in 'duedatecountdown' span.
# This is currently located in the breadcrumb headers.
# note that the dueDateLayout is internatinoalized below.
# Here document is used to support the substitution into the javascript below.
# ..which unforunately necessitates escaping the $'s in the javascript.
# There are several times of importance
#
# serverDueDate - The absolute time at which the problem expires.
# serverTime - The server's time when the problem finished computing.
# clientTime - The client's time...as close to serverTime as possible.
# The clientTime will be slightly later due to
# 1. The latency between problem computation and
# the first network action.
# 2. The time required between the page load-start and the actual
# initial javascript execution that got clientTime.
# These are used as follows:
# The difference between clientTime and serverTime are used to
# correct for differences in clock settings between the browser's system and the
# server's.
#
# The difference between clientTime and the time at which the ready() method
# starts executing is used to estimate latencies for page load and submission.
# Since this is an estimate, it is doubled. The latency estimate + one minute
# is used to determine when the countdown timer turns red to warn the user
# to think about submitting.
