I have an issue Regarding time Zone I am fetching data from mysql
and want to convert according to given time zone let say mysql data return time is
2014-05-20 16:32:52
and here is my code
$dateTime = new DateTime($driverPickUpTime);
$dateTime->setTimezone(new DateTimezone('Asia/Riyadh'));
$temp = $dateTime->format(CNOC_DATE_TIME_FORMAT);
the issue is this code return different time on different server like on dev and live having same DB connection there is 2 hours difference. i want same time on both server
new DateTime() accepts a timezone as second parameter. By providing the timezone that is stored in the database you should always get the correct result:
$dateTime = new DateTime($driverPickUpTime, new DateTimeZone( /*enter DB timezone here*/ ));
I suggest you get the time from mysql as UTC.. see mysql UTC_TIME and UTC_DATE here and then switch timezones using PHP

I am trying to get the local time using php. I wrote two different versions, but they both give the wrong time
date_default_timezone_set('UTC');
$now = new DateTime();
echo $now->getTimestamp();
Another way
date_default_timezone_set('America/New York');
echo strtotime("now")."<br/>";;
$now = new DateTime();
echo $now->getTimestamp();
In both cases I get the time 4 fours ahead of my local time. There is any other way to get the local time?
DateTime::getTimestamp() returns unix timestamp. That number is always UTC. What you want is format the date according to your time zone.
$dt = new DateTime("now", new DateTimeZone('America/New_York'));
echo $dt->format('m/d/Y, H:i:s');
Or use a different date format, according to what you need.
Also, you can use DateTime library for all your date needs. No need to change server's default timezone every time you want to fetch the date.
Simply use function date_default_timezone_set(). Here is example:
<?php
date_default_timezone_set("Asia/Dhaka");
echo date('d-m-Y h:i:s A');
?>
Hope it will help,
Thanks.
You need to use javascript because you want the value of time from the client. PHP is a server-side language that evaluates on the server and sends results to the client. So if you try to pull a date/time using a PHP function, it's going to pull the date from the server, which is not always in the client's timezone.
You can do this in a javascript function and then reference the value in the display.
var thisDateTime = new Date();
If you don't want to use timezone you can use this mix of windows and php commands:
<?php
$D = exec('date /T');
$T = exec('time /T');
$DT = strtotime(str_replace("/","-",$D." ".$T));
echo(date("Y-m-d H:i:s",$DT));
?>
I'm wondering why nobody has mentioned localtime(time()); in PHP with indexed key array result or localtime(time(), true); with associative key array result.
For the record, I found the only solution to read the real hour of the machine is to read the information outside of PHP (javascript, shell or other processes). Why?
For example, let's say we have an hour based in daily-saving. What if the timezone of the OS (Windows in my case) is not in sync with the timezone of PHP, I mean, it could be calculated differently. Or maybe the machine is using a different hour and it is ignoring the daily-saving hour.
Right now, my zone is UTC -4 Santiago 9:35 pm (with daily saving). However, PHP considers as 10:35 PM (using localtime,time,date and DateTime).
If anyone here wanted to get the local time according to the user's timezone (dynamically), then you can consider the following code:
$ip = $_SERVER['REMOTE_ADDR'];
$ipInfo = file_get_contents('http://ip-api.com/json/' . $ip);
$ipInfo = json_decode($ipInfo);
$timezone = $ipInfo->timezone ?? "UTC";
$dt = new DateTime("now", new DateTimeZone($timezone));
echo $dt->format('Y-m-d H:i:s');
The above code will get the user's local timezone and print the time according to that.
If you wanted to test the above code on your localhost then make sure to hard code your IP address there because the API can't provide you the timezone based on your local address (127.0.0.1), but the above code works fine on the
live server.
For Localhost, do:
$ip = '-------'; //your IP address
You can solve this problem by using localtime() function or through date_default_timezone_set() function.

i think this must help you..
I am using godaddy hosting service and I can manage local time, I have to use the server default time that is America/Phoenix.
Even if i am using date_default_timezone_set("Asia/Kolkata");
function in my config file then also there is no difference in time and godaddy people are not ready to help me with, I am tired of calling this guys but no response, I hate them all.
Is there any means I can get my local time using any function or any external API?
I am using this code
//set time zone india
date_default_timezone_set("Asia/Kolkata");
$timezone = date_default_timezone_get();
echo "The current server timezone is: " . $timezone;
$date = date('m/d/Y h:i:s a', time());
echo $date."<br>";
and the output that I am getting is
The current server timezone is: Asia/Kolkata05/14/2014 12:06:26 am
Even if it is 4:38 pm here...
date_default_timezone_set should work for PHP functions like date, however I'm going to hazard a guess that you're having problems with date/time elements in a database such as MySQL.
I know I've had similar problems before, when trying to get everything on UTC instead of Europe/London...
When you've established the connection to your database, be sure to run this query:
SET time_zone = 'Asia/Kolkata';
This, in addition to date_default_timezone_set, should solve your problems. However, if you're using DATETIME columns, then those will not be fixed. TIMESTAMP columns will be automagically fixed to the new timezone because they are saved as UTC internally and converted upon retrieval.
You shouldn't touch date_default_timezone_set. The proper way to do that would be to use DateTimeZone object. Something like this:
$now = new \DateTime('now', new \DateTimeZone('Asia/Kolkata'));
echo $now->format(\DateTime::ATOM);
So, the idea is that you create an object in a timezone of server and then convert it to your timezone
Our current hosting company is based in Canada so obviously their times are different to the UK.
Is there any way in PHP to display the Date/Time but get it from a different server if i specify the IP?
you can use date_default_timezone_set (see documentation) function to set your actual script time to whatever you need
example for Rome
date_default_timezone_set('Europe/Rome');
Using timezones would be a better idea.
$now = new DateTime(null, new DateTimeZone('America/Toronto'));
$now->setTimezone(new DateTimeZone('Europe/London'));
echo now->format('Y-m-d H:i:s);
So I have a site with a comments feature where the timestamp of the comment is stored in a MySQL database. From what I understand, the timestamp is converted to UTC when stored, then converted back to the default timezone when retrieved. In my case, my server is in the Central Daylight Time timezone (CDT).
I have a plan to get the timezone from each user via entry form. I just wanted to know how to convert the TIMESTAMP value into the user's timezone.
First, would I convert from UTC to local timezone? Or CDT to local timezone?
Secondly, how would I go about doing that in PHP? Would I just do:
$userTimezone = new DateTimeZone($userSubmittedTimezoneString);
$myDateTime = new DateTime($storedTimestamp, $userTimezone);
...or is that not correct?
Date/time/datetime values are stored in MySQL as you supply them. I.e. if you INSERT the string 2012-04-17 12:03:23 into a DATETIME column, that's the value that will be stored. It will be converted internally into a timestamp which may or may not be accurate (see below), but when you query for the value again, you'll get the same value back out; the roundtrip is transparent.
Problems may occur if you try to do time calculations inside SQL. I.e. any operation that requires SQL to take the timezone and/or the server time into account. For example, using NOW(). For any of those operations, the timezone and/or server time should be set correctly. See Time Zone Problems.
If that doesn't concern you and you only need to do calculations in PHP, you only need to make sure you know from which timezone to which timezone you want to convert. For that purpose it can be convenient to standardize all times to UTC, but it is not necessary, as timezone conversions from any timezone to any other timezone work just as well, as long as you're clear about which timezone you're converting from and to.
date_default_timezone_set('Asia/Tokyo'); // your reference timezone here
$date = date('Y-m-d H:i:s');
/* INSERT $date INTO database */;
$date = /* SELECT date FROM database */;
$usersTimezone = new DateTimeZone('America/Vancouver');
$l10nDate = new DateTime($date);
$l10nDate->setTimeZone($usersTimezone);
echo $l10nDate->format('Y-m-d H:i:s');
There is no reliable way to get the user's timezone. Timezone information is not sent in HTTP headers. The best that you could do is either:
Match the IP address againsta geographic database
-or-
Use Javascript to get the time set on the user's computer and either send that to the server (AJAX) or make the time string on the client.
$timezone = new DateTimeZone('America/Vancouver');
$date = new DateTime(date('m/d/Y h:i:s a', time()));
$date->setTimeZone($timezone);
echo $date->format('l F j Y g:i:s A')."\n";
Replace new DateTime(date('m/d/Y h:i:s a', time())); with new DateTime("UTC Time");
You can create a new DateTimeZone() object for each user input.
The way to do it is by using javascript. I think the best way to do it is by storing the users GMT into his cookies, and retrieving it on the PHP process form.
<script language="javascript">
function TimeZoneCookie()
{
var u_gmt = (-(new Date().getTimezoneOffset()))/60;
var o_date = new Date("December 31, 2025");
var v_cookie_date = o_date.toGMTString();
var str_cookie = "utimezone="+u_gmt;
str_cookie += ";expires=" + v_cookie_date;
document.cookie=str_cookie;
}
//---------------------
TimeZoneCookie();
</script>
u_gmt explained:
Date().getTimezoneOffset() returns the offset to GMT-0 in minutes
Since getTimezoneOffset() will return the offset to GMT-0 and not from GMT-0 we'll need to turn it around. How? simple, just by knowing that -*-=+ & -*+=-. If you know basic math, you already know this principle.
As I said in step 1 getTimezoneOffset() will return the offset in minutes, so we just divide it by 60, so we can get the gmt offset format.
Result: (-(new Date().getTimezoneOffset()))/60
Now retrieve the cookie in PHP:
<?php
$user_timezone = $_COOKIE['utimezone'];
?>
I am having an issue with php date() function.
When I save the date in mysql datebase the hours shows 4 hours less than my current time.
My php code is below: $add_date = date("Y-m-d H:i:s");
It saves the time in database as
2011-08-03 07:51:26
But is should show
2011-08-03 13:22:26
Can anybody tell me how to fix it
Thanks
You have to set a valid time zone - it seems you don't have an appropriate time zone set up in php environment for your location.
Check out
http://www.php.net/manual/en/function.date-default-timezone-set.php
It should give you a clue how to set up the correct time zone in php.
#Mujahid If the printed time and the saved time are the same it probably means your server is not in the same timezone as you. With that said, you have to manually set the default timezone for your PHP script at the top of the file, or get the DateTime by defining your timezone explicitly. Here's the code:
$dateTime = new DateTime("now", new DateTimeZone('America/Los_Angeles'));
$add_date = $dateTime->format("Y-m-d H:i:s");
echo $add_date;
Here's a list of time zones that PHP supports, just find yours and replace America/Los_Angeles with it.
http://php.net/manual/en/timezones.php
Here's a good tutorial on PHP DateTime and DateTimeZone...
http://ditio.net/2008/06/03/php-datetime-and-datetimezone-tutorial/
Hope this helps. Good luck.
Make the time zone setting of the MySQL server and the web server the same.
this will add hosted server time not local time
$add_date = date("Y-m-d H:i:s");
use strtotime() to add hours and minutes
$newdate = date("Y-m-d H:i:s",strtotime('+ 5 hours 30 minutes'.$row['db_date']));
