strtotime format

$date = '25/05/2010';
$date = str_replace('/', '-', $date);
echo date('Y-m-d', strtotime($date));

python from timestamp to string

from datetime import datetime

timestamp = 1545730073
dt_object = datetime.fromtimestamp(timestamp)

print("dt_object =", dt_object)
print("type(dt_object) =", type(dt_object))

# Output

dt_object = "2018-12-25 09:27:53"
type(dt_object) = <class 'datetime.datetime'>
