PHP - It Is Not Safe To Rely On The System's Timezone Settings. Help!
Hey everyone. I was hoping to get some help on something that I am working on.
First, I hope this is the right place to post this. Please forgive me if this is the wrong forum. I am new to PHP as I work mostly as a Sys Admin. Recently, I have been working on a project running a number of applications on PHP. I configured a box and a PHP application that has a web interface. Everything looks good except for when I log into the web interface. I am greeted with this message: Code: [Select] Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Los_Angeles' for 'PDT/-7.0/DST' instead in /usr/local/www/base/base_main.php on line 138n I have done a lot of research trying to figure out what is causing this. A lot of websites and posts on other sites suggested that the fix would be to make a change in the php.ini file in the : date.timezone section. I did make that change, however the issue still persists. I decided to make a quick test.php file to read the configuration file and see if I can get additional information. I opened up the test.php web page and made sure I was reading the correct configuration file. Which, according to the test page, I am. Moving forward, under the DATE section of the test.php file, I see this: Code: [Select] Warning: phpinfo() [function.phpinfo]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Los_Angeles' for 'PDT/-7.0/DST' instead in /usr/local/www/apache22/data/test.php on line 2 Which is what I see as well when I log into the application's interface. Under that date section, it says the following: Code: [Select] Default timezone -- America/Los_Angeles Which is my timezone. For a test, I changed the "date.timezone" section in my php.ini file to "America/New York", restarted apache and loaded the config file backup. Looking at the date section again, the error is still there and the DEFAULT TIMEZONE is still pointing to "America/Los_Angeles". So it appears that its not reading my config file or I am completely missing something. Here is the full section of the DATE part of the test.php file: Code: [Select] date/time support enabled "Olson" Timezone Database Version 2011.4 Timezone Database internal Default timezone America/Los_Angeles Directive Local Value Master Value date.default_latitude 31.7667 31.7667 date.default_longitude 35.2333 35.2333 date.sunrise_zenith 90.583333 90.583333 date.sunset_zenith 90.583333 90.583333 date.timezone no value no value I have been trying to figure this out for the past few day with no luck. I was hoping someone might be able to help me out here. Thanks for the help.

Then, every time time I do a query in a model, mysql_connect(); // MySQL connects using the default values from the ini_sets we did. mysql_query($query); mysql_close(); The reason behind this, would be to avoid passing database variables to objects/models etc or defining constants. Maybe there's a better way? I'm looking into database abstraction. hello dear PHP-Fans - greetings to you - and a happy new year!! i set up a WAMP-System on my openSuse 11.4 system.

Love to hear from you greetings db1 Quote Strict Standards: DateTime::__construct() [datetime.--construct]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Chicago' for 'CDT/-5.0/DST' instead in /home/elliottw/public_html/login/inc/conn.inc.php on line 45 And the code I am using is: $timezone = new DateTimeZone("Europe/London"); $date = new DateTime(); $date->setTimezone($timezone); $dateTime = $date->format('H:i:s d/m/Y'); $sqlDateTime = $date->format('Y-m-d H:i:s'); I've come to the end of my tether. I can't see anything wrong with this, searched Google and I'm starting to go crazy (partly due to the Caffeine and staring at code for 4 hours). Any help would be greatly appreciated! Cheers. I am in need of a script that can detect a visitors timezone with out using geoip and with out the user providing the information. Any help on this or references would be greatly appreciated. I just upgraded from 5.2.x to 5.3.3 this morning, and am now confronted with the "infamous" Code: [Select] It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/New_York' for '-5.0/no DST' instead in C:\Inetpub\wwwroot\ATSTest\sys\class\class.calendar.inc.php on line 98 Previously I just let php pull the system time to keep everything accurate with DST. Now that I'm having to use the date.timezone setting in php.ini, how can I tell it to factor in DST, or do I now have to manually perform a calculation in my methods/functions to check and adjust? Or does it automagically recognize the DST by setting it to Code: [Select] date.timezone = America/New_York (yeah, right...what are the odds of *that*? hey im writing a page that does the timezones for 5:00 around the world and i found this template the only thing is it didnt include the timezone.php file the js is loading this new Ajax('timezone.php?tz='+String(timezone),{onComplete:tzCLB, method: 'get'}).request(); what it does is retrieves a list of countries from that file i think. How and what would i need to do to make a timezone.php that would get the countries. Thanks Hi, I am trying to get the date and time that a particular table was last updated, which the code below does, but it doesn't seem to be putting it in the correct timezone, it is 5 hours behind, anyone know why this is? or how i can fix it? Thanks Code: [Select] <?php date_default_timezone_set('Europe/London'); $query = "SELECT UPDATE_TIME FROM information_schema.tables WHERE TABLE_SCHEMA = 'tffdb' AND TABLE_NAME = 'test_team_points'"; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_assoc($result); echo $row['UPDATE_TIME']; ?> instead of js alert displaying the timezone offset, i would like the content of get_time_zone_offset() to be used as a php variable.
<script type="text/javascript">
function get_time_zone_offset( ) {
var current_date = new Date();
return -current_date.getTimezoneOffset() / 60;
}
alert("The local time zone is: GMT " + get_time_zone_offset());
</script>
How would I change the current timezone used within a php script? The method I usually use, date_default_timezone_set() is undefined on my webhost, so I am trying to find another way. Developing apps is great until I have to start dealing with blasted timezones. For some reason this aspect of it always does my head in. At the moment I'm storing all dates in the DB as GMT with the format Y-m-d H:i:s. I figure it's good to be consistent and store dates in GMT then convert to the users desired timezone. So I allow users to choose there timezone, based off the defined PHP timezones that can be used with the DateTimeZone class. My problem, however, arises with the whole syncing of times. Let's say I post something right now. The date gets stored in in the database as: 2012-04-14 02:35:49 Now I'm in GMT +10 (possibly the greatest of timezones ), so I've set my timezone in my settings as Australia/Melbourne and when displaying date/times locally I do something like this: Code: [Select] public static function local($user, $date, $format = 'F j, Y, h:ia') { $date = new DateTime($date); return $date->setTimezone(new DateTimeZone($user->timezone))->format($format); } So running the stored date above through my method gives me a date like this: April 14, 2012, 12:35pm Awesome. My question is: I noticed that on say, Twitter, when you change your timezone your tweet dates don't change. They remain as the date/time of my actual timezone, regardless of what I set it too. With my implementation however, if I change my timezone to GMT +12 (Fiji) my post is now posted at: April 14, 2012, 02:35pm So is what I'm doing right? My head has about had it. Thanks. using this below is it safe against hackers? Code: [Select] $post_id = intval($_GET['report']); if ($post_id < 1) message($lang_common['Bad request']); query: Code: [Select] $result = $db->query('SELECT subject, forum_id FROM '.$db->prefix.'topics WHERE id='.$topic_id) or error('Unable to fetch topic info', __FILE__, __LINE__, $db->error()); should i escape my $topic_id ? Code: [Select] $stick_topic = isset($_POST['stick_topic']) ? '1' : '0'; does this need to be escaped while entering the database or no because the values could only be 1 or 0 ? srry it's just i got hacked so i am trying to do my security #1 Hi all I've got an issue with time zones for displaying information. I'm hoping someone might know of a guide that would cover the following. I'm struggling to find one! Basically I have many online events to list in many different timezones. Users may wish to use their time zone to display information in. What I would like to do is store a timestamp and timezone for each event, then will need (I think!) to convert all to a single timezone in order to list them chronologically. From that I would then convert them into the user's desired timezone and display to the page. The idea to is avoid changes in time throughout the year, so it does it all automatically. Any links, tips, words of advice very gratefully received! I have a Xampp Timezone Error Error Warning: strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings.

I have fields for date assigned and date completed. Both are timestamp with timezone columns in a postgresql table My goal is to have a cron job which selects the records from the table on the dates the invoices are due and includes the proper jobs-- i.e. the ones that are completed prior to the due date and time(5PM on the first and 15th of each month) That is where I am running into confusion as to how to store the time/tz and then select it in the future so everything is correct This is what I have right now: Code: [Select] $assignmenttype, "miles" => $miles, "notes" => $notes, "dateassigned" => "{$assignmenty1}-{$assignmentm1}-{$assignmentd1} $time1:00 America/Chicago", "datecompleted" => "{$completedassignmenty1}-{$completedassignmentm1}-{$completedd1} $time2:00 America/Chicago"); $res = pg_insert($conn, 'assignments', $invoicearray); I have an idea, which I'm trying to realise, im using the time() function to store the timestamp within my db...and within the db I have a timezone column (which contains the timezone selected by that user). So I'd like to display $row['timestamp'] (the stored timestamp generated by time()) to the specified timezone, how would that work? <?php //$timestamp = timestamp generated by the time() function //$timezone = the timezone to convert $timestamp too function convert_time($timestamp, $timezone) { //$new_timestamp = do something to adapt $timestamp to $timezone //return the formatted/readable date... return date('D M Y H:i', $new_timestamp); } ?> Hello all. Just wanted to run this past you guys to see if I am missing anything important. I am making a script that I plan to allow a lot of other people around the web to use, so I want to make sure it's as bullet proof as possible. I am passing two values and grabbing them with a _GET, one is a big number, and the other is only letters and 8 characters long. her's my code so far. Code: [Select] <?php $clan = $_GET['clanid']; // make sure its an INT //if(isint($clan)){ if(ereg("[^0-9]", $clan)){ //im an int. echo ("ERROR Invalid CLANID"); die; } // make sure its a 8 letter only word. $style=$_GET['style']; // cut style down to 8 characters long. $style=substr($style, 0, 8); if(ereg("[^a-zA-Z]+", $style)) { // Contains only letters. echo("ERROR Invalid STYLE NAME"); die; } ?> to my noob php eye's it looks pretty solid, I cant think of any way a malicious user could get past it, but like I said, thought I would run it past you guys first , you can never be to careful. Advice please. I am setting up a new machine here and I can't remember which to download. What information do you need to be aware of to know whether to install 'non thread safe' or 'thread safe'. I did some googling but didn't find anything that was clear. And is 5.3 good to go or should I stick with 5.2. Thanks in advance for your input! I have a button that uses $_POST to send information to another page. The data is in a hidden input so it's not possible for users to change information. I have nothing to check if the data is correct on the other page. Is it still possible for people to change the $_POST data though? Or somehow send false $_POST data to the other page? Hi guys, I have been using the same code for years now to include my default page and pull content into my layouts.
I found the code online and its a bit confusing so was just wondering if its still safe to use, and is it all needed nowadays?
or is there a simpler way i could be doing this?
Thanks for any help
