Import Time    # mainly for time Check 
# output current timestamp 
Print (the time.time ())
 # acquires the current date 
Print (The time.strftime ( ' %% Y-M-% D ' ))
 # stamp transfer date 
Print (The time.strftime ( " % D%% Y-M-% H:% M:% S " , time.localtime ()))

print('=====================')

Import datetime   # most of the time for calculating 
Print (datetime.datetime.now ())

# Calculation time of ten minutes after the 
# constructor: the datetime.timedelta (Days = 0, = 0 seconds The, = 0 microseconds, milliseconds = 0, = 0 minutes, hours = 0, = 0 weeks) 
# where parameters are optional The default value is 0 
NEWTIME the datetime.timedelta = (= 10 minutes )
 Print (datetime.datetime.now () + NEWTIME) # current time plus 10 minutes

# Calculated after 10 days time 
one_day = A datetime.datetime (2019,10,13 )
new_date = datetime.timedelta(days=10)
print(one_day+new_date) # 2019-10-23 00:00:00
