将字符串值转换为时间戳格式

import time
from datetime import datetime

date_string = "2022-01-01 12:00:00"
timestamp = int(datetime.strptime(date_string, "%Y-%m-%d %H:%M:%S").timestamp())
print(timestamp)

const dateString = "2022-01-01 12:00:00";
const timestamp = new Date(dateString).getTime() / 1000;
console.log(timestamp);

import java.text.SimpleDateFormat;
import java.util.Date;

String dateString = "2022-01-01 12:00:00";
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = dateFormat.parse(dateString);
long timestamp = date.getTime() / 1000;
System.out.println(timestamp);
