I am getting an error message when testing converting a UTC timestamp string to datetime using strptime.

ValueError: time data '2025-03-12T23:00:00.000Z' does not match format '%Y-%m-%dT%H:%M:%S.%f%Z'

Here is a simple test that

from datetime import datetime, timezone

utc_string = "2025-03-12T23:00:00.000Z"

print(f'Time in: {utc_string}')

time_utc = datetime.strptime(utc_string, '%Y-%m-%dT%H:%M:%S.%f%Z').replace(tzinfo=timezone.utc)

print(f'Time out: {time_utc}')

Remove the '%' before Z, Z does not need the %:

time_utc = datetime.strptime(utc_string, '%Y-%m-%dT%H:%M:%S.%fZ').replace(tzinfo=timezone.utc)
