python - Are these two formatting date methods really equivalent?

Wednesday, 20 March 2019

It seems that:

time.strftime("%Y-%m-%d %H:%M:%S")
#2017-01-12 10:46:57

datetime.datetime.today().strftime("%Y-%m-%d %H:%M:%S")
#2017-01-12 10:46:57

are equivalent. When I read many questions/answers here, or tutorials or documentation, some of them use the former, some the latter.

Are they 100% equivalent? When to prefer the one or the other?

PS: the latter seems to be equivalent to datetime.date.fromtimestamp(time.time()), but is this equivalent to time.strftime(...)?
