convert timestamp to date in custom commands

i am creating custom commands in django. i have a problem with conversion timestamp to date by methods like fromtimestamp. i have such error: line 13, in handle timest_conv = datetime.fromtimestamp(timest) OSError: [Errno 22] Invalid argument

this is my class with handle

class Command(BaseCommand):
    def handle(self, *args , **options):
        r = requests.get('https://api.metals.live/v1/spot/silver').json()
        price = r[0]['price']
        timest = r[0]['timestamp']
        timest_conv = datetime.fromtimestamp(timest)
        print(price,timest, timest_conv )

        return

Answer

The timestamp is expressed in milliseconds since January 1st, 1970. You thus should divide these by 1’000 to retrieve the timestamp:

timest_conv = datetime.fromtimestamp(int(timest)/1000)

for the given sample timestamp, we get:

>>> datetime.fromtimestamp(1634309968403/1000)
datetime.datetime(2021, 10, 15, 16, 59, 28, 403000)
