Timezone japan php

Why does this work?

date_default_timezone_set("Australia/Currie");

But this doesn"t seem to take any effect at all?

date_default_timezone_set("UTC");

This value doesn"t change when setting the timezone to lớn UTC:

emang đến date("Y-m-d H:i:s", time());

I"m using php 5.2.13, và the timezone of my VPS is:

$server_tz = date_default_timezone_get(); emang lại $server_tz; //outputs "America/Guayaquil"

This is the original code:

eđến time() . "
"; date_default_timezone_set("UTC"); emang lại time() . "
";

Output:

1317235130 1317235130

How bởi you know it hasn't taken any effect? – CanSpice Sep 28 "11 at 17:59
Because time() prints the same original value and my hệ thống is not on UTC tz. – Andres SK Sep 28 "11 at 18:02

echo date('Y-m-d H:i:s T', time()); & see what the timezone is. – Herbert Sep 28 "11 at 18:12

Herbert the date will just convert the time stamp lớn a defined date, the output will be the same for the values before and after the date_default_timezone_set('UTC'); – GTodorov Nov 25 "14 at 18:25

The problem is that you"re displaying time(), which is a UNIX timestamp based on GMT/UTC. That’s why it doesn’t change. date() on the other h&, formats the time based on that timestamp.

A timestamp is the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT).

echo date("Y-m-d H:i:s T", time()) . "
"; date_default_timezone_set("UTC"); emang lại date("Y-m-d H:i:s T", time()) . "
";

UTC is a valid identifier then. Try the new code I posted & let us know what it says. – Herbert Sep 28 "11 at 18:31
this is the new output: America/Guayaquil ---- 2011-09-28 13:32:39 ECT ---- 2011-09-28 18:32:39 UTC ---- 2011-09-29 04:32:39 EST – Andres SK Sep 28 "11 at 18:32

It works fine. Notice the differences in hours và the UTC in the second cống phẩm. I don't know what you were doing, but it works just fine. Perhaps you should show your actual code in your question. – Herbert Sep 28 "11 at 18:35

i posted the original code... it works when using the date() function, but it doesn't when using the plain time() function... maybe it was that, right? – Andres SK Sep 28 "11 at 18:40

UTC is definitely a valid timezone. It is simply an abbreviation for Coordinated Universal Time. In addition, rethành viên that date_default_timezone_mix accepts one of the following values:
