Answer 2

import pytz
import datetime
import time
def utc_to_local(utc_time_str, utc_format='%Y-%m-%dT%H:%M:%SZ'):
    local_tz = pytz.timezone('Asia/Chongqing')
    local_format = "%Y-%m-%d %H:%M"
    utc_dt = datetime.datetime.strptime(utc_time_str, utc_format)
    local_dt = utc_dt.replace(tzinfo=pytz.utc).astimezone(local_tz)
    time_str = local_dt.strftime(local_format)
    return int(time.mktime(time.strptime(time_str, local_format)))
