如何将字符串时间戳转换为特定时区的时间戳

import datetime
import pytz

def convert_timestamp_to_timezone(timestamp, target_timezone):
    # 将字符串时间戳转换为日期时间对象
    datetime_obj = datetime.datetime.strptime(timestamp, "%Y-%m-%d %H:%M:%S")

    # 获取目标时区的时差
    target_tz = pytz.timezone(target_timezone)
    target_offset = target_tz.utcoffset(datetime.datetime.now()).total_seconds()

    # 计算特定时区的时间戳
    target_timestamp = datetime_obj.timestamp() + target_offset

    # 将特定时区的时间戳转换为字符串形式
    target_datetime = datetime.datetime.fromtimestamp(target_timestamp)
    target_datetime_str = target_datetime.strftime("%Y-%m-%d %H:%M:%S")

    return target_datetime_str

timestamp = "2022-01-01 12:00:00"
target_timezone = "Asia/Shanghai"
converted_timestamp = convert_timestamp_to_timezone(timestamp, target_timezone)
print(converted_timestamp)
