Timezone - Date_default_timezone_set() Eastern Standard Time (EST)?

Apr 5, 2011

Is there an official, un-deprecated timezone that PHP5 recognizes for Eastern STANDARD time--not Eastern DAYLIGHT time?Short story long :-PWow, I can't believe that PHP makes such a cluster-floogen out of setting the time.I would like to use PHP5's date_default_timezone_set() to set the timezone for my script. I want to use standard time. I do not want my script to observe daylight savings time. I do not want to have to use gmtime() and subtract 60*60*5 seconds each time my program writes a time. I don't want to save that value to a variable either. Setting the default timezone is more elegant and makes the script more portable to other servers and locales.Unfortunately PHP requires I use one of their stupid "official timezones" when setting the default time zone. There is an "America/New_York" but I have no idea if it or any of the official PHP timezones observe Daylight savings time. Through experimentation, I discovered that "America/New_York" does observe DST. "America/Panama" is EST and thus does not observe DST... but what if Panama should ever change their mind about DST in the future? (They observed DST in 1908)Because Panama could always change their mind; I just want to use the GMT or UTC offset. there but is very USA-centric so I understand why it is deprecated. "Ect/GMT-5" is there too and I have absolutely no idea why that is deprecated. If you ask me, all the place name timezones should be deprecated and the GMT timezones un-deprecated... but get this... "Ect/GMT-5" is actually wrong! I had to use "Ect/GMT+5" to get USA's Eastern Standard Time. I'm pretty sure I'm not 5 hours ahead of England here on the East Coast.

Answered?No one really answered the question. So I guess I'll answer it myself. "No, there is no, un-deprecated timezone that PHP5 recognizes for Eastern STANDARD time" A lot of folks told me I that should store dates as UTC time and translate them to local time when I pull them out of storage--something I already know. The problem is, I was hired to only fix this little part of the script and I doubt the guy is going to let me re-write his whole code which he's been using since the dawn of PHP supposedly.I will reluctantly give credit to the dude who shows you how to correctly store and retrieve times so future folks searching for this learn how to do this the right way.

Show Time / Date To Reflect Eastern Standard Time

Apr 5, 2007

my web host is located on the west coast i live on the east coast so if my page shows the date:

$day = date(d);
$mth = date(m);
$yr = date(y);
echo $day . "-" . $mth . "-" . $yr;

i shows the date as of west coast time. so the time now is 1:40am april 6, 2007 my page will still show april 5, since west coast is 3 hours back. (10:40pm apr 5) how do i compensate for this time zone difference? i want my time / date to always reflect eastern standard time.

Altering Time Per Timezone And Displaying Time One Hour From Current Time?

I am printing out a date as such

echo date('l jS of F Y h:i:s A');

The server is on west coast and I am on east coast. It displays west coast time and I want to adjust -3 hours for east coast time. I have seen it done before but cannot find reference to how it is done right off hand. The server has PHP 4 installed if that makes a difference. I also want to display the time one hour ahead such as echo "one hour from now will be (php)";

Change From Local Time To GMT For Unix Format Time?

May 20, 2011

Using PHP/mysql I implemented a form for saving in the db a time in unix format using the function mktime. The view form displays the time in a readable format using date function. Only now I discovered that I was using local time and not GMT (UTC) time as requested. The changes are quite easy in the sw changing mktime for gmmktime and date for gmdate. But the question is if there is a way to convert the time already in the DB (in unix format) from local time to gmt time.

Time Difference Change Over Time

Nov 27, 2007

Is there a way to print the time different depending on how long the time has been. So like if the user has not been logged in for 24 hours or more... it will say 1 day rather than 24 hours. And if its less than 1 hour it will say it in minutes... and if its greater than 1 hour but less than 1 day it will say minutes and hours?

This is my query which i have done so far but don't know how to do the above checking!

//get register date and now date
$GetLoginDate = mysql_query("SELECT DATEDIFF(NOW(), LoginDate) AS LastLogin FROM userregistration
WHERE  UserID='{$_SESSION['Current_User']}'")
or die(mysql_error());
$lastlogin = mysql_fetch_assoc($GetLoginDate);

Get Server Time - Timezone

my server time is (simple date in bash Sun Aug 29 10:37:12 EDT 2010 when I run the code php -r "echo date('Y-m-d H:i:s');" I get: 2010-08-29 10:37:10 but when I execute a php script that has echo date('Y-m-d H:i:s'); I get a different time- since php thinks the timezone is UTC (server time is EDT). My php.ini file has no timezone set, and I wouldnt like to change anything- as I have no idea what affect it would have on other sites that run on this server. Is there a simple way to get the server time- at the timezone that is set for the server?

Show Time In Different Timezone

May 20, 2007

My webserver is hosted in England and I'm in the US.  So all the time is showing up a couple hours ahead of my timezone.  I can't edit the php.ini file or none of that so I was wondering how would I go about changing the php scripts on my pages to display the time and date as EST. 

At 11 PM my time Saturday may 19 it said it was "Sunday May 20, 4:00 am"  So I can't just do something that changes that hour, I need it to display the correct date aswell.

Central Standard Time In The U.S. (CST Timezone -6).

Mar 7, 2007

the server that hosts my PHP pages has its clock set to Greenwich Mean Time (GMT timezone 0). I need for my PHP scripts to have access to my local time which is Central Standard Time in the U.S. (CST timezone -6). Note: daylight savings time _is_ observed in my state.

I have looked all over a PHP algorithm that would convert GMT to CST but
have so far not been successful. Does anyone have such an algorithm lying around that they could post?

Setting Time According To Timezone From Database

Apr 1, 2011

I want to make a system which displays time dependant on the timezone in a particular country. E.g. a table in my database contains country names in one field, and in the column next to it, it will contain GMT-compared timezones like -0100 or -0200. What I need to do on the webpage then is set current GMT time ($time), and then pull the information from the database and alter $time to be GMT -1 or GMT -2.

So far I have this code:..............

which seems to do the job, and I could enter into the database 'Antarctica/South_Pole' rather than the GMT-/+ time. Would this do the job OK in the long run? Also, using this method, would Daylight saving times be worked out OK?

Timezone - How To Display Local Time

Our server is set to GMT time so the hour does not keep jumping around in spring and autumn. However, during summer time, it is annoying that all the times are displayed an hour out.

How do I get and display the time, taking into account the local timezone in PHP (especially when the server thinks the local timezone is GMT).

or, How do I know if an area is using "summer time" at the moment?

Server Returns Time From Different Timezone?

Jun 14, 2011

I have read many forum posts on the use of date(), time(), and $_SERVER['REQUEST_TIME']. Here is my issue. My server is set for Mountain Standard Time (MST). I can see this in the server confiq. in php.ini the timezone is set to AMERICA/Phoenix. However when I run a script with just date() the time returned is clearly Eastern time. My script is stripped down to only return that function. I keep testing different inputs, I have tried to only call the $_SERVER['REQUEST_TIME'] and I keep getting Eastern (my timezone). What am I missing?

What I am trying to do: I have a script that should only display a dialogue box/input box at a certain time based on the server time, and the end of an offer time stored on my db. So I call the server time to compare to the end time on the db. The script works fine but actual time returned by date() messes it up by a couple hours.

Showing The Right Time Based On Viewer's Timezone?

Jan 2, 2010

My goal: To output dates on pages that match the user's timezone.Why I want this: Records are stored based using GMT. I don't want them thinking a message arrived for them at a different time than they actually arrived. Also the user shouldn't have to perform math to figure out when the message was received.Recently I was told I should store the date and time in MySQL using the date/time data type so that I can later use MySQL's built in functions to manipulate the data. I can then convert the date to show to the viewer and convert back when storing.This process has been giving me the most trouble so far.I've researched for the best way to find the user's timezone and it looks like I'll have to use Javascript for that. I'm unaware how more professional or time tested scripts accomplish this.

The way that I came up with (which doesn't work all too well) is to instead of have PHP print the date to the screen, it hands the date over to Javascript in which Javascript is to get the viewer's timezone, make the change to the date and then Javascript write's the date to the screen.One problem that I'm running into doing it this way is after the page has been sitting for a few minutes. If I hit refresh the dates jump forward several hours, if I hit refresh again they jump back, again and they'll jump forward. I can keep doing this and watch the hours seesaw back and forth each time I hit refresh. Another problem is that I have yet to figure out how to format a Javascript date so in the date/time field I have this:

Fri Jan 01 2010 22:04:31 GMT-0500 (Eastern Standard Time)Another way may be to ask the logged in user upon registration what their timezone is and format the dates that way, although many of the more professional sites don't seem to do this and they seem to get the time's right.I'm sure that many of you have faced the same dillemma,

TimeZone Problem - Retrieve The Server Date/time

print"Today's date: ".$date_array['mday']."/".$date_array['mon']."/".$date_array['year'];
print"Server Time: ".$date_array['hours'].":".$date_array['minutes'].":".$date_array['seconds'];

Getting User Selected Timezone Date Time With Only Offset

Feb 16, 2011

In my website, every user has to select their timezone when they register . The user database table has a column named timezone and its value is one of the keys in the following array:

$zones = array(
'UM12' => -12,
'UM11' => -11,
'UM10' => -10,
'UM95' => -9.5,

[Code].....

Currently, the web server has default_timezone set to UTC and all date time values in the database which are in mysql datetime format are stored in this timezone.

So, for a date time to display correctly according to the timezone of a user, I need a way to do the conversion. This is what I have come up so far:

$timezone_offset=$zones[$user_row->timezone];
$utc_timestamp=strtotime($user_row->registered_on);

As you can see, I need a function that somehow accepts these two parameters and give me the date time in the timezone of the user.

Tell If A Timezone Observes Daylight Saving At Any Time Of The Year?

Oct 19, 2009

In PHP, you can tell if a given date is during the Daylight Savings Time period by using something like this:

$isDST = date("I", $myDate); // 1 or 0

The problem is that this only tells you whether that one point in time is in DST. Is there a reliable way to check whether DST is in effect at any time in that timezone?

Brisbane, Australia does not observe daylight savings at any time of the year. All year around, it is GMT+10. Sydney, Australia does, from October to March when it changes from GMT+10 to GMT+11.

if there would be some existing method, or a way to implement a method which works as such:

timezoneDoesDST('Australia/Brisbane'); // false
timezoneDoesDST('Australia/Sydney'); // true

MySQL Date / Time Query To A Server In The WRONG Timezone

Mar 7, 2010

I never thought I'd wanna do something this sophisticated: so even though I'm in the midwestern US, I went with a website host located in sunny California. Okay here is the problem. Say I set an appointment time in a mysql table, in a date/time field. The appointment time (SHOWTIME) is, say '2010-03-07 17:30:00' (5:30pm local time here in Milwaukee). Now, I want to do a query of appointments like this: SELECT if(SHOWTIME > Now(), 1, 0) as APPT, NOTES FROM showings ORDER BY SHOWTIME

This way, if the value of APPT is less than the system time (Now()) I can use the resulting value of 0 as a signal to color the resulting row in the displayed table, grey, or otherwise signal that the appointment time has passed. BUT the system, being in California is two hours behind me, and therefore the lines don't show up the way I want them until two hours later. Is there an arguement that can be put in the MySQL query that would correct this?

Store Time Ranges In MySQL And Determine If Current Time Is Within Time Range?

I have a database table storing opening hours of a shop as a time range in TIME format.

To determine if the shop is currently open or closed, I will run the query:

SELECT *
FROM shop

Now I am stumped. How should I proceed? I can have a pair of 'hours_open' and 'hours_close' for each day, eg: 'mon_hours_open', 'mon_hours_close', 'tue_hours_open', 'tue_hours_close' ...But how do I handle opening hours that go past midnight like 9pm-5am?

Twitter Timezone And Created_at Values To Calculate What Time Zone User Is In?

I'm trying to estimate a twitter user's location based on the time_zone or created_at value in a given tweet object. However it seems that all created_at values I've come across are just in a pointless localised time and the time zone they supply isn't in the most helpful format example tweet

"created_at":"Thu Jun 02 14:41:24 +0000 2011"
"time_zone":null
OR
"created_at":"Sun Jan 09 05:03:52 +0000 2011"
"time_zone":"Mountain Time (US & Canada)"

Both of these times aren't in UTC time and the time_zone isn't in any particular standard format with the rest of the world I'm probably coming across really annoying, I'm tired and hot and been looking for this solution for too long.

Codeigniter: Set Date / Time Based On Users Timezone / Location Globally In A Web App?

Feb 16, 2010

I have just realised if I add a particular record to my MySQL database - it will have a date/time of the server and not the particular user and where they are located which means my search function by date is useless! As they will not be able to search by when they have added it in their timezone rather when it was added in the servers timezone.

Is there a way in Codeigniter to globally set time and date specific to a users location (maybe using their IP) and every time I call date() or time() that users timezone is used.

What I am actually asking for is probably how to make my application dependent on each users timezone?

Maybe its better to store each users timezone in their profile and have a standard time (servers time) and then convert the time to for each user?
