What is the easiest way to get current GMT time in Unix timestamp format?

Question

Python provides different packages (datetime, time, calendar) as can be seen here in order to deal with time. I made a big mistake by

Answer 1

#First Example:
from datetime import datetime, timezone    
timstamp1 =int(datetime.now(tz=timezone.utc).timestamp() * 1000)
print(timstamp1)

Output: 1572878043380

#second example:
import time
timstamp2 =int(time.time())
print(timstamp2)

Output: 1572878043

• Here, we can see the first example gives more accurate time than second one.
• Here I am using the first one.
