How to convert microsecond timestamp to readable date?

Question

I want to convert the following timestamp - "1571299045371875" which is in microseconds to a date format of "2019-10-17T07:57:35.333333Z".

I've tried using:

date_time = datetime.utcfromtimestamp(timestamp)
st = date_time.strftime("%Y-%m-%dT%H:%M:%S.%fZ")

But this gives me [Errno 22] Invalid argument, when trying to convert the timestamp. Converting a timestamp of milliseconds works fine, but I can't lose precision.

Is there any way to convert microsecond timestamp?

Answer 1

given your expected output, you should use a datetime object that resembles UTC:

from datetime import datetime, timezone

ts = 1571299045371875
dtobj = datetime.fromtimestamp(ts/1e6, tz=timezone.utc)
# datetime.datetime(2019, 10, 17, 7, 57, 25, 371875, tzinfo=datetime.timezone.utc)

isostring = dtobj.isoformat()
# '2019-10-17T07:57:25.371875+00:00'

# or as specified in the question
isostring = dtobj.isoformat().replace('+00:00', 'Z')
# '2019-10-17T07:57:25.371875Z'
