Concantenate two string and convert to datetime pandas python : I am using latest version of pandas and python 3.5

I have  a CSV file with two columns DATE and TIME both are string

DATE: 07Jan2015

TIME: 0:00:00

I need to concatenate DATE and TIME and convert the result to datetime or timestamp but the DATE must be in following format

DATE FORMAT: 01/07/2015

So the result should look like this: 01/07/2015 0:00:00

I am using pandas to import the CSV

Your help is always appreciated

Thanks
