如何基于时区在php中获取Unix时间戳 [英] How to get Unix timestamp in php based on timezone

问题描述

先编码

    echo time() . '<br/>';
echo date('Y-m-d H:i:s') . '<br/>';
date_default_timezone_set('America/New_York'); 

echo time() . '<br/>';
print_r($timezones[$timezone] . '<br/>');
echo date('Y-m-d H:i:s') . '<br/>';

在上面的代码中，日期是根据时区打印的，但是即使设置了默认时区，unix时间戳也是相同的

In the above code the date is printed according to timezone but unix timestamp is same even after setting default timezone

推荐答案

Volkerk提供的答案(表示时间戳始终基于UTC)是正确的，但是如果您确实需要解决方法(制作基于时区的时间戳) )看看我的例子.

The answer provided by Volkerk (that says timestamps are meant to be always UTC based) is correct, but if you really need a workaround (to make timezone based timestamps) look at my example.

<?php

//default timezone
$date = new DateTime(null);
echo 'Default timezone: '.$date->getTimestamp().'<br />'."\r\n";

//America/New_York
$date = new DateTime(null, new DateTimeZone('America/New_York'));
echo 'America/New_York: '.$date->getTimestamp().'<br />'."\r\n";

//Europe/Amsterdam
$date = new DateTime(null, new DateTimeZone('Europe/Amsterdam'));
echo 'Europe/Amsterdam: '.$date->getTimestamp().'<br />'."\r\n";

echo 'WORK AROUND<br />'."\r\n";
// WORK AROUND
//default timezone
$date = new DateTime(null);
echo 'Default timezone: '.($date->getTimestamp() + $date->getOffset()).'<br />'."\r\n";

//America/New_York
$date = new DateTime(null, new DateTimeZone('America/New_York'));
echo 'America/New_York: '.($date->getTimestamp() + $date->getOffset()).'<br />'."\r\n";

//Europe/Amsterdam
$date = new DateTime(null, new DateTimeZone('Europe/Amsterdam'));
echo 'Europe/Amsterdam: '.($date->getTimestamp() + $date->getOffset()).'<br />'."\r\n";
?>

获取常规时间戳并添加UTC偏移量
