event is an ActiveRecord object and created_at is a Time instance,
thus trying to see if falls within a TemporalExpression doesn't work
as Time doesn't have a date_precision method.
Not sure this is exactly what you need but hopefully it gets the point
across. If you run the code below as-is, it will raise:
NoMethodError: undefined method 'date_precision' for Mon Nov 06
07:38:00 GMT 2006:Time
However if the code modifying Time is uncommented then passing Time
objects to still_there? appear to work fine.
Hope it all makes sense,
Paul.
