Question

当我登录时以及当我退出时，我试图保持跟踪..我正在创建一个在线关注系统。我写了这些代码来追踪..但它没有在我当地的时间跟踪..当我在上午10点唱歌时它显示在下午4点签到..我该怎么办？

    $result = $_GET["result"];

    $date = date('Y-m-d');
    $day = date('l');
    $min = date('i');
    $hour = date('H');

    $min = $min - 5;
    if($min<0){ $hour=$hour-1; $min=$min+60;}
    $time = $hour.":".$min;
    $settime = $time;
    $settime1 = date('H:i');
?>

Answer 1

使用date_default_timezone_set函数

 date_default_timezone_set("Asia/Calcutta");

 $login_time = date("Y-m-d H:i:s");

Answer 2

PHP安装在服务器和默认UTC时区，您需要根据当地时区更改时区，将date_default_timezone_set("time_zone");功能置于脚本顶部

<?php
date_default_timezone_set("Asia/Bangkok");
echo date_default_timezone_get();
echo date('Y-m-d H:i:s')
?>

TIMEZONE list

Answer 3

你在哪个时区？你应该使用

设置默认时区

date_default_timezone_set('Asia/Kolkata');

在使用date函数之前，此行应位于文件的顶部。详情阅读setting default timezone和timezone regions

Answer 4

你可以这样做：

date_default_timezone_set('Asia/Kolkata');//set your time zone 

echo date('Y-m-d H:i:s');// get the date

在此处查看设置默认时区：http://php.net/manual/en/function.date-default-timezone-set.php 和时区：http://php.net/manual/en/timezones.php

Answer 5

DateTime::getTimestamp()返回unix时间戳。该数字始终为UTC。你想要的是根据你的时区格式化日期。

$dt = new DateTime("now", new DateTimeZone('Asia/Kolkata'));

echo $dt->format('m/d/Y, H:i:s');

或根据您的需要使用不同的日期格式。

此外，您可以使用DateTime库来满足您的所有日期需求。每次要获取日期时都无需更改服务器的默认时区。
