#This file is for little helper functions that need to be accessed by several applications
from django.utils import datetime_safe
#This is a patch that allows for formatting dates before 1900, seriously
#This function takes a date and three boolean values associated with that date and outputs a
#formatted date that only displays to the end user the components of the date that are "known"
#It is typically used in a view to format a date from a given model in that application.
#It could also be used to create a 'phantom' table in the database that holds a phantom date
#using the property() function.
#If you want to change how the dates are formated see the python date format options list at
# http://docs.python.org/library/datetime.html#strftime-strptime-behavior
