从DateTime获取时区

pip install pytz

from datetime import datetime
import pytz

# 创建一个datetime对象
dt = datetime.now()

# 设置时区
tz = pytz.timezone('Asia/Shanghai')

# 将datetime对象转换为指定时区的时间
dt_shanghai = tz.localize(dt)

# 打印时区
print(dt_shanghai.strftime('%Z'))

const dt = new Date();
const tz = Intl.DateTimeFormat().resolvedOptions().timeZone;

console.log(tz);

import java.time.ZonedDateTime;
import java.time.ZoneId;

public class Main {
    public static void main(String[] args) {
        ZonedDateTime zdt = ZonedDateTime.now();
        ZoneId zoneId = zdt.getZone();

        System.out.println(zoneId);
    }
}
