Set the default of a DateTime Field to the current date/time

The default behavior for my ATs was that a DateTimeField using the CalendarWidget would only have the year filled in.  I wanted the value to be set to the current date and time.  I had no special requirements for accuracy, time zones, etc. 

The three step process is:

1)  Add this line to the area where you declare imported modules.  Note that I am lazy and used the asterisk.  You might be more conscientious and actually import the specific module necessary:

from DateTime.DateTime import *

2) In the Schema, make a DateTimeField and specify a default_method to populate the field:

    DateTimeField('dateAdded',
        searchable = 1,
        required = 0,
        default_method = 'getDefaultTime',
        widget = CalendarWidget(
            label = 'Date Added'
        ),
    ),

3) In the class definition code, skip to near the bottom and add a new method called getDefaultTime:

    def getDefaultTime(self):
        return DateTime()

That's it.  Your new instances should now be populated with something that approximates the current date and time.
