import datetime as dt

import time as tm

time returns the current time in seconds since the Epoch. (January 1st, 1970)

tm.time()

1511435382.15

Convert the timestamp to datetime.

dtnow = dt.datetime.fromtimestamp(tm.time()) dtnow

datetime.datetime(2017, 11, 23, 11, 10, 3, 160514)

Handy datetime attributes:

dtnow.year, dtnow.month, dtnow.day, dtnow.hour, dtnow.minute, dtnow.second # get year, month, day, etc.from a datetime

(2017, 11, 23, 11, 10, 3)

timedelta is a duration expressing the difference between two dates.

delta = dt.timedelta(days = 100) # create a timedelta of 100 days

delta

datetime.timedelta(100)

date.today returns the current local date.

today = dt.date.today()

today - delta # the date 100 days ago

datetime.date(2017, 8, 15)

today > today-delta # compare dates

True
