Setting locale time

[PyraX]

Hi, I was wondering if anyone had a script that can get the locale time of the users computer so that the server can use that instead of the "America/Denver" that it seems to keep defaulting to?

 

Thanks

Here is something I came up with a while ago to get the client's local date/time -

<?php
if (isset($_GET['offset'])) {
$minutes = $_GET['offset'];
echo "GMT offset (in minutes, from the browser): ". $minutes ."<br />\n";
echo "GMT: ". gmdate("Y-m-d H:i:s") ."<br />\n";

$local = gmmktime(gmdate("H"),gmdate("i")-$minutes); // adjust GMT by client's offset

echo "Calculated client's date/time: ". gmdate("Y-m-d h:i:s a",$local) ."<br />\n";
} else {
echo "<script language='javascript'>\n";
echo "var d = new Date();\n";
echo "location.href=\"${_SERVER['SCRIPT_NAME']}?offset=\" + d.getTimezoneOffset();\n";
echo "</script>\n";
exit();
}
?>

A simple google search turned up this. How weird

 

http://us2.php.net/localtime

 

localtime() returns an array so try this

 

<?php

$Time = localtime();

 

echo "Hours:" . $Time[2] . "<br> Minute:" . $Time[1] . " <br> Second:" . $Time[0];

?>

 

do

 

print_r(localtime())

 

to see the full array and what other information it has

That gets the local time on the server and has nothing to do with the question that was asked.

Thanks so much PFMaBiSmAd now just need to set the server time with the right offset. Do you know the command?

[PFMaBiSmAd]

Any script that uses date/time functions that are dependent on the time zone can set the time zone using the date_default_timezone_set() function using parameters like - 'Etc/GMT+1', 'Etc/GMT+10', 'Etc/GMT-13', ...

It seems to be reverting to defaults on every page change here is my script

 

<?php 
if (!strstr(date_default_timezone_get(),"Etc/GMT")) {
	echo date_default_timezone_get(); // returns America/Denver 
if (isset($_GET['offset'])) {

	$offset = ss($_GET['offset']) / 60;
	if ($offset >= 0) {
		$offset = "+".$offset;
	}

	date_default_timezone_set('Etc/GMT'.$offset);
	$_SESSION[TIMEOFFSET] = $offset;
	echo date_default_timezone_get(); // returns Etc/GMT-10 


} else {
	echo "<script language='javascript'>\n";
	echo "var d = new Date();\n";
	echo "location.href=\"${_SERVER['SCRIPT_NAME']}?${_SERVER['QUERY_STRING']}&offset=\" + d.getTimezoneOffset();\n";
	echo "</script>\n";
	exit();
}
}
?>

Because the code causes a page to request itself to pass the value to the server, you should only get the value if you don't already know it (save the value in a session or a database.) Give the following a try -

 

<?php
session_start();
if(!isset($_SESSION['time_zone'])){
// if the time zone is not known,  get it from the client
if (isset($_GET['offset'])) {
	$minutes = $_GET['offset'];
	$hours = $minutes/60;
	$tz = sprintf('%+d', $hours);
	$_SESSION['time_zone'] = $tz;
	date_default_timezone_set("Etc/GMT{$_SESSION['time_zone']}");

	// the following four lines are for demonstration purposes and can be removed
	echo "GMT offset (in minutes, from the browser): $minutes, Timezone = Etc/GMT$tz<br />\n";
	echo "GMT: ". gmdate("Y-m-d H:i:s") ."<br />\n";
	$local = gmmktime(gmdate("H"),gmdate("i")-$minutes); // adjust GMT by client's offset
	echo "Calculated client's date/time: ". gmdate("Y-m-d h:i:s a",$local) ."<br />\n";
} else {
	echo "<script language='javascript'>\n";
	echo "var d = new Date();\n";
	echo "location.href=\"${_SERVER['SCRIPT_NAME']}?offset=\" + d.getTimezoneOffset();\n";
	echo "</script>\n";
	exit();
}	
} else {
// this visitor's time zone is already known, set the default timezone for all date/time calculations
date_default_timezone_set("Etc/GMT{$_SESSION['time_zone']}");
}
echo "Server time by setting timezone: " . date("h:i:s a");
?>

Works perfectly, Thank you so much
