Overview

Time, date and timestamps are handled with the time and datetime modules, available in the Standard Library.

Additionally, the dateutil module provides useful extensions.

time Module

Sleep

from time import sleep
sleep(1)

datetime Module

Time Interval with timedelta

from datetime import datetime
dt1 = datetime.datetime(2022,3,27,13,27,45,46000) 
dt2 = datetime.datetime(2022,6,30,14,28) 
tdelta = dt2 - dt1 
print(tdelta) 
print(type(tdelta))

To get the total number of seconds in timedelta, use total_seconds():

from datetime import datetime
t0 = datetime.now()
...
t1 = datetime.now()
print((t1 - t0).total_seconds())

now Time

from datetime import datetime

now = datetime.now()

current_time = now.strftime("%H:%M:%S")
print("Current Time =", current_time)

#
# To display YYYY-mm-dd:
#
print(f'{now.strftime("%Y-%m-%d")}')
#
# equivalent
#
print(str(datetime.date.today()))
