[SOLVED] How to get UTC time in PHP 4?

[phpvasu]

How can I get UTC time in PHP 4?

 

[nathanmaxsonadil]

you could use this if you were using php 5.1 and higher

date_default_timezone_set('UTC');

but I dont think it possible on php 4

[phpvasu]

We don't have PHP 5 installed in our server. Getting PHP 5 on the server is not an immediate solution.

I need to get UTC time in PHP 4 at the moment.

 

Any ideas?

Well, you could use the O or Z format characters to get a differance between your timezone and GMT and work with that.

 

www.php.net/date

Rather like:

 

<?php
$timestamp = time();
$offset = date('Z');
$gmt_timestamp = $timestamp - $offset;
echo date('H:i:s',$gmt_timestamp);
?>

Ben,

echo gmdate('H:i:s'); is also yielding the same result. How different is your method?

 

Will it be accurate to gmdate then?

[GingerRobot]

Hmm, didn't notice that was a php 4 function too. Its exactly the same, just much shorter!

before concluding, one more question.

 

Is there any difference between GMT time and UTC time?

 

[GingerRobot]

Not that im aware of. A google define seems to suggest they are the same too

thanks Ben.

 

So, I will go with gmdate then.
