Fortunately Python has a dedicated timedelta class for that purpose ( just like Java has Period and PHP has DateInterval ). That makes calculations simple ( and with Python's overloaded operators also intuitive ).
Unfortunately timedelta has no dedicated method to initialize it from a string, like datetime's .strptime(), so you have to spoonfeed it with integers :

CODE --> Python

from datetime import datetime, timedelta
import re

with open('Tester_V.txt') as file:
    for line in file:
        part = line.split(', ')

        first = datetime.strptime(part[0], '%m/%d/%Y %I:%M:%S %p')
        second = datetime.strptime(part[1], '%m/%d/%Y %I:%M:%S %p')

        deltapart = [int(one) for one in re.findall(r'\d+', part[2])]

        delta = timedelta(hours = deltapart[0], minutes = deltapart[1], seconds = deltapart[2], microseconds = deltapart[3])

        print('%s + %s = %s' % (first, delta, first + delta))
        print('%s + %s = %s' % (second, delta, second + delta))
