am getting continue this error in cakephp even i ave set timezone in php.ini but it gives 500 internal server error
Warning: strtotime(): 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 the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home1/allinal6/public_html/telecom/lib/Cake/Cache/CacheEngine.php on line 61
Thanks in advance
That warning is unrelated to your 500 internal server error. However, in order to remove that warning, as seen on How do I set default timezone in cakephp? go into /app/config/core.php and find the line that calls date_default_timezone_set(); (normally commented out when you first download CakePHP.) Uncomment it and add your desired timezone.

my current timezone is Asia/Karachi and when i retrieve table data from mysql it gives me (actual time - 5 hours)
for eg:
mysql column value: '2021-04-21 01:34:57'
and when i retrieve from laravel DB::table('table_name')->get()->toArray();
it gives following :2021-04-20 20:34:57
and changing my timezone doesn't change anything either.
so is there something else i'm missing ?
btw i created following route for checking my current timezone
$app->get('/timezone', function () {
return date_default_timezone_get();
});
and it gives same what is saved in my env i.e(Asia/Karachi) but this doesn't change the result i get from mysql even if i change it to some other timezone like Asia/Kolkata.
I tried researching on this but didn't get any suitable answer.
i tried alot of things to solve this issue like
adding env variables APP_TIMEZONE="Asia/Karachi" (did not work)
also i tried adding DB_TIMEZONE="+05:00" (this worked in my local but not on stagging)
finally i saw somewhere that someone else had exact same issue resolving this and he did it by adding the hours using carbon which also worked for me
'posted_at' => Carbon::parse($record->posted_at)->addHours(5)->toDateTimeString(),
i know this is not the optimal solution but this was the only solution that worked so i had to go with it.

If you store a TIMESTAMP value, and then change the time zone and retrieve the value, the retrieved value is different from the value you stored. This occurs because the same time zone was not used for conversion in both directions. The current time zone is available as the value of the time_zone system variable.
As far as I know, you have a couple things to consider:
The timezone of your Laravel/Lumen app
This can be found found in config/app.php -> timezone.
The timezone of your MySQL server
You can retrieve this using:
mysql> SELECT ##global.time_zone, ##session.time_zone;
The timezone of the server itself
If the mySQL query above returns SYSTEM, it means it uses the system timezone setting, which for Debian/Ubuntu etc you can check using:
cat /etc/timezone
From my experience, you can most often leave the system/mySQL timezones intact and only set the correct timezone in your Laravel config. I know it caused me a headache the first time I had to figure out how this actually worked.
I lived in philippines and when I'm inserting date in my database, It's inserting less 13 hours in my database. For example, our datetime here is 02-11-2016 21-04-00, when I insert, it's inserting 02-11-2016 08-04-00
I already used this:
date_default_timezone_set('Asia/Manila');
But no luck. I already put the website in my domain.
This should be done by
date_default_timezone_set('Asia/Manila');
Make sure you are uploading the correct files.
If it doesn't work; try making a page for error handling, then echo a variable that will set the time for this timezone, if it works. Use that variable instead.
The timezone you set is used for PHP as Bimal said, you need to check the server time as well, because time is very sensitive part of the information you don't want to miss or play with.
I've been in that situation couple of weeks back, there are two ways to fix it:
Set the server timezone to the correct timezone.
If the time difference is always and EXACTLY 13 hours, use this approach:
$new_time = date("Y-m-d H:i:s", strtotime('+13 hours')).
I ended up using the second method as the first one was not an option for me.
Best of Luck.
If I am not wrong you have pasted php function which will just set time_zone for php not for my_sql. mysql has global time_zone variable which can be set. You should use SET GLOBAL time_zone = timezone; or SET time_zone = timezone;.
If you dont have direct control of your DB server in that case you can pass the 2nd statement i.e set time_zone=...; as 1st statement.
Alternatively you can also use the convert_tz function to convert an already stored value.
I want to know what is the time zone that is currently set in the MySQL server. I do not have administrator rights to the computer I am using so I've tried the method by checking the registry.
I am doing a table with a timestamp column and I noticed the time stamped is different than the one on my computer's time. Is there any reason for this? How do I check what timezone it is on the MySQL server? How do I change it to match my local/computer's time?
You can set the timezone (if you know your offset) for the session by using
set session time_zone = '+00:00';
and to revert to the system default
set session time_zone 'SYSTEM';
In an SQL timestamp column, SQL automatically converts the time to UTC before storing it, using the session's current time offset. It will be the machine's time offset unless you change it (3). Depending on your server's settings (sql.ini), it may or may not always concert back to the expect timezone. This probably explains the time discrepancy.
To get the current timezone offset, try executing
SELECT ##session.time_zone;
To manually override the SQL timezone for the rest of a particular session, execute the following, replacing 00:00 with your desired offset:
SET ##session.time_zone = "+00:00";
Have a look at the system_time_zone system variable.
This may help:

You can set the system time zone for MySQL Server at startup with the --timezone=timezone_name option to mysqld_safe. You can also set it by setting the TZ environment variable before you start mysqld. The permissible values for --timezone or TZ are system dependent. Consult your operating system documentation to see what values are acceptable.
You can convert a given timestamp to UTC (or any other TZ you want) with CONVERT_TZ
SELECT CONVERT_TZ(NOW(),##session.time_zone,'GMT');
Note that I use NOW() as simple demonstration, you would put in the timestamp you wanted to convert.
By the same token, you could convert a timestamp in your local TZ to the system
SELECT CONVERT_TZ($timestamp,'Your Time Zone' ##session.time_zone);
To check your shared server
<?php
echo date_default_timezone_get();
?>
To change
<?php
date_default_timezone_set("Africa/Addis_Ababa");
echo date_default_timezone_get();
?>
When I set useLegacyDatetimeCode=false in my JDBC connection properties, I get this error message:
java.sql.SQLException: The server timezone value 'CET' represents more
than one timezone. You must configure either the server or JDBC driver
(via the serverTimezone configuration property) to use a more specifc
timezone value if you want to utilize timezone support. The timezones
that 'CET' maps to are: Europe/Tirane, Europe/Andorra, Europe/Vienna,
Europe/Minsk, Europe/Brussels, Europe/Sofia, Europe/Prague,
Europe/Copenhagen, Europe/Tallinn, Europe/Berlin, Europe/Gibraltar,
Europe/Athens, Europe/Budapest, Europe/Rome, Europe/Riga,
Europe/Vaduz, Europe/Vilnius, Europe/Luxembourg, Europe/Malta,

Europe/Uzhgorod, Europe/Zaporozhye, Europe/Simferopol,
Europe/Belgrade, Africa/Algiers, Africa/Tripoli, Africa/Casablanca,

I understand what the message is telling me, but I'm not sure what to do about it. I don't have any way of knowing what time zone the MySQL server is running in (this is software that my customers install, and the servers are not managed by me).
I need to set this property to false to fix MySQL time zone bugs.
You need to pass an additional parameter like this:
db=jdbc:mysql://localhost/db?user=me&pass=secret&useLegacyDatetimeCode=false&serverTimezone=Europe/Vienna
I have a shared hosting mySql instance which has it's system_time_zone set to Pacific Standard Time and it's time_zone variable set to System, hence effectively it's running on Pacific Standard Time.
i.e. I've run the following command to find this out:
SELECT version( ) , ##time_zone , ##system_time_zone , NOW( ) , UTC_TIMESTAMP( )
I would like to change the default mySql database / local mySql DB time-zone to GMT/UTC time. I tried to run, SET time_zone = '+0:00', and this does execute successfully!
However, this does not seem to affect the time_zone variable, when I check the state of ##time_zone. I've looked at another post dealing with similar issue How to set MySQL to use GMT in Windows and Linux and I also checked the MySql documentation, with little progress. Since I am on a shared-hosting solution, I have limited access and I don't have access to more than what my PhPMyAdmin mySql functionality has on offer.
I wonder if there is any way to change the default_time-zone from within an SQL query, or do I need to fall back to the command line (to which I don't have access to, unfortunately).
Thanks for your help and advice,
Martin
In short, MySQL actually stores 'datetime' data type fields internally as UTC.
However, PhpMyAdmin shows you the dates using the server default time, hence your confusion.
For example, try adding this line before your SQL statement in PhpMyAdmin:
SET ##session.time_zone='+00:00';
SELECT * FROM MY_TABLE
See the MySQL documentation for further details, or the answer in this post: How to correctly set mysql timezone

For shared hosting, you have to ask support-guys to help you and change default time zone for you? I had similar problem with Arcor hosting-provider, called them and they fixed it. Before that, I found temporary solution in date_default_timezone_set() from PHP code. Probably the best solution is to ask someone who has privilege to change that parameter.
<?php
date_default_timezone_set('UTC'); //define local time
$date=date('l jS \of F Y h:i:s A'); //type of time shown
$conn=mysql_connect("localhost","root","") or die('Could not connect!'); //your database connection here
$db_selected = mysql_select_db('databasename', $conn); //select db
$result=mysql_query("INSERT INTO table (date) VALUES ('$date')", $conn);
?>
Simply sent the time as VARCHAR into db hope it helps and sorry for syntax errors (if there are any).
