我们可以使用date函数设置默认时区:

<?php
    date_default_timezone_set("Asia/Kolkata");
    echo "Today is " . date("Y/m/d") . "<br>";
    echo "Today is " . date("Y.m.d") . "<br>";
    echo "Today is " . date("Y-m-d") . "<br>";
    echo "Today is " . date("l");
    echo "The time is " . date("h:i:sa");
?>

date_default_timezone_set('Europe/Warsaw');
echo("<p class='time'>".date('H:i:s')."</p>");
echo("<p class='date'>".date('d/m/Y')."</p>");

您的国家时区:支持的时区列表

date_default_timezone_set('Asia/Kolkata');

$dateYmd = date('Y-m-d');
echo "Current Year Month Day: $dateYmd";

本年月日:2022-01-03

$datehms = date('h:i:s');
echo "Current Hour Minute Second: $datehms";

当前小时分秒:11:05:38

 $date = new DateTime('now', new DateTimeZone('Asia/Kolkata'));
 echo $date->format('d-m-Y H:i:s');

更新

 //Also get am/pm in datetime:
 echo $date->format('d-m-Y H:i:s a'); // output 30-12-2013 10:16:15 am

对于日期格式，PHP date() Function很有用。

日期格式也取决于:

echo date("d/m/Y H:i:sa"); // 13/04/2017 19:38:15pm

Use:

$date = date('m/d/Y h:i:s a', time());

它的工作原理。
