print(now.day) # 8
print(now.hour) # 11
print(now.minute) # 30
print(now.second) # 35

# 时间差 timedelta
delta = datetime.datetime(2021,4,16,1,2,3) - datetime.datetime(2021,4,10,0,0,0)
print(delta) # 6 days, 1:02:03

print(delta.seconds) # 3723

delta2 = datetime.timedelta(926,56700)
print(delta2.days) # 926
print(delta2.seconds) # 56700

# 可以给datetime加上（或减去）一个或多个delta
start = datetime.datetime(2021,1,1)
new = start + datetime.timedelta(12) - 2*datetime.timedelta(1,3600)
print(new) # 2021-01-10 22:00:00
