This is just some confusion about imports, abetted by the naming
scheme of the datetime module.

The datetime module contains a datetime class. The full name of the
class is datetime.datetime. If you "import datetime" then you have to
use the full name. Another way to import is "from datetime import
datetime". Now the name datetime refers to the class and you can just
use its name alone. So, try
  d = datetime(*(time.strptime('20080321_113405', format)[0:6]))

You can read about the import statement here:
