feb_16_2019 = datetime.date(year=2019, month=2, day=16)
feb_16_2019 = datetime.date(2019, 2, 16)
print(feb_16_2019) #2019-02-16

time_13_48min_5sec = datetime.time(hour=13, minute=48, second=5)
time_13_48min_5sec = datetime.time(13, 48, 5)
print(time_13_48min_5sec) #13:48:05

timestamp= datetime.datetime(year=2019, month=2, day=16, hour=13, minute=48, second=5)
timestamp = datetime.datetime(2019, 2, 16, 13, 48, 5)
print (timestamp) #2019-01-02 13:48:05

Python provides a module named datetime to deal with dates and times.
