strftime
I was working with jq when I was reading some documentation which referenced strftime, when googling I found this Python resource, which helped me, even though I should probably have found one in JavaScript anyway, this one worked for me.
strftime can convert a DateTime object to a string in a given format.
from datetime import datetime
now = datetime.now() # current date and time
year = now.strftime("%Y")
print("year:", year)
month = now.strftime("%m")
print("month:", month)
day = now.strftime("%d")
print("day:", day)
time = now.strftime("%H:%M:%S")
print("time:", time)
date_time = now.strftime("%m/%d/%Y, %H:%M:%S")
print("date and time:",date_time)
