Ah, I see. You need to create a new adapter module in this case, using the adapter_imagineeficcom.py as a template should help you out. For the datetime parsing I would check out the Python documentation
here. Once you figure out the correct format string you need, you can use the makeDate function contained in the base_adapter.py module (compare line 61, 247 and 250 in the adapter_imagineeficcom.py file).
EDIT: Ah now I actually understand the context of your question, I wasn't aware you were trying to develop your own adapter. The advice above should be able to help you along hopefully.
