1. import datetime

3. print('Timestamp: {:%Y-%m-%d %H:%M:%S}'.format(datetime.datetime.now()))  
4. print('Timestamp: {:%Y-%b-%d %H:%M:%S}'.format(datetime.datetime.now()))  
5. print('Date now: %s' % datetime.datetime.now())  
6. print('Date today: %s' % datetime.date.today())  
7.   
8. today = datetime.date.today()  
9. print("Today's date is {:%b, %d %Y}".format(today))  
10.   
11. schedule = '{:%b, %d %Y}'.format(today) + ' - 6 PM to 10 PM Pacific'  
12. schedule2 = '{:%B, %d %Y}'.format(today) + ' - 1 PM to 6 PM Central'  
13. print('Maintenance: %s' % schedule)  
14. print('Maintenance: %s' % schedule2)  

Output: 

Timestamp: 2017-05-22 19:36:31
Timestamp: 2017-May-22 19:36:31
Date now: 2017-05-22 19:36:31.683160
Date today: 2017-05-22
Today's date is May, 22 2017
Maintenance: May, 22 2017 - 6 PM to 10 PM Pacific
Maintenance: May, 22 2017 - 1 PM to 6 PM Central
