Try the <a href="http://www.php.net/manual/en/datetime.gettimezone.php" rel="noreferrer">getTimezone and setTimezone</a>, see the example

(But this does use a Class)

UPDATE:

Without any classes you could try something like this:

<pre><code>$the_date = strtotime("2010-01-19 00:00:00");
echo(date_default_timezone_get() . "&lt;br /&gt;");
echo(date("Y-d-mTG:i:sz",$the_date) . "&lt;br /&gt;");
echo(date_default_timezone_set("UTC") . "&lt;br /&gt;");
echo(date("Y-d-mTG:i:sz", $the_date) . "&lt;br /&gt;");
</code></pre>

NOTE: You might need to set the timezone back to the original as well

Do this way:

or simply 

<pre><code>gmdate('Y-m-d H:i:s')

to get "NOW" in UTC.

If you have a date in this format YYYY-MM-HH dd:mm:ss, 
you can actually trick php by adding a UTC at the end of your "datetime string" and use strtotime to convert it.

<pre><code>date_default_timezone_set('Europe/Stockholm');
print date('Y-m-d H:i:s',strtotime("2009-01-01 12:00"." UTC"))."\n";
print date('Y-m-d H:i:s',strtotime("2009-06-01 12:00"." UTC"))."\n";
</code></pre>

This will print this:

<pre><code>2009-01-01 13:00:00
2009-06-01 14:00:00
</code></pre>

And as you can see it takes care of the daylight savings time problem as well.

A little strange way to solve it.... :)

As an improvement on <a href="https://stackoverflow.com/a/2095812">Phill Pafford's answer</a> (I did not understand his 'Y-d-mTG:i:sz' and he suggested to revert timezone). 
So I propose this (I complicated by changing the HMTL format in plain/text...):

<pre><code>&lt;?php
header('content-type: text/plain;');
$my_timestamp = strtotime("2010-01-19 00:00:00");

// stores timezone
$my_timezone = date_default_timezone_get();
echo date(DATE_ATOM, $my_timestamp)."\t ($my_timezone date)\n";

// changes timezone
date_default_timezone_set("UTC");
echo date("Y-m-d\TH:i:s\Z", $my_timestamp)."\t\t (ISO8601 UTC date)\n";
echo date("Y-m-d H:i:s", $my_timestamp)."\t\t (your UTC date)\n";

// reverts change
date_default_timezone_set($my_timezone);
echo date(DATE_ATOM, $my_timestamp)."\t ($my_timezone date is back)\n"; 
?&gt;
</code></pre>

I am in need of an easy way to convert a date time stamp to UTC (from whatever timezone the server is in) HOPEFULLY without using any libraries.

php convert datetime to UTC

我需要一个简单的方法来转换一个日期，时间戳到UTC (从任何时区的服务器)，希望不使用任何库。
