I wants to display singapore time. I have tried out like this,
<?php echo date("l dS of F Y h:i:s A");
but when inserting this value to a column of data table (with datatype-datetime ) it shows the time as 0000-00-00 00:00:00. Please help
You need to insert with mysql date time format. In PHP which is equivalent to,
date("Y-m-d H:i:s")
Note: Issue is not related to Time Zone, but you can set default time zone to Singapore using
date_default_timezone_set('Asia/Singapore'); on top of your file.
date_default_timezone_set('Asia/Singapore');
$todayDate=date("Y-m-d H:i:s");
date_default_timezone_set('Asia/Singapore');
look at this for default_time_rimezone
to get the timezone.
<?php
date_default_timezone_set("Asia/Bangkok");
echo date_default_timezone_get();
?>
There are two methods to display current timestamp. Either you use "localtime" PHP method to display the current local time in an Array OR you can use DateTimeZone to display the specific timezone date-time. Here is the code ..
<?php
// Echo the local time in an array.
print_r(localtime(time(),true));
// Set the manual time zone if you wants to display other time zone dateTime (For Example : Singapore).
$from = new DateTimeZone('GMT');
$to = new DateTimeZone('Asia/Singapore');
$currDate = new DateTime('now', $from);
$currDate->setTimezone($to);
echo $currDate->format('Y/m/j H:i:s');
?>
write date_default_timezone_set('Asia/Singapore'); before displaying the date.
for inputting the value into database, use the date("Y-m-d H:i:s") format in php to match the column, or make the column type as varchar(50) to store date as string.
You can use this
http://ir2.php.net/manual/en/datetime.construct.php
// Current date/time in the specified time zone.
$date = new DateTime(null, new DateTimeZone('Asia/Singapore'));
echo $date->format('Y-m-d H:i:sP') . "\n";
try with date_default_timezone_set()
<?php
date_default_timezone_set( 'Europe/Paris' ) ;
echo date( "l dS of F Y h:i:s A" ) ;
date_default_timezone_set( 'Asia/Singapore' ) ;
echo date( "l dS of F Y h:i:s A" ) ;
?>

I have a datetime column in MySQL.
How can I convert it to the display as mm/dd/yy H:M (AM/PM) using PHP?
If you're looking for a way to normalize a date into MySQL format, use the following
$phpdate = strtotime( $mysqldate );
$mysqldate = date( 'Y-m-d H:i:s', $phpdate );
The line $phpdate = strtotime( $mysqldate ) accepts a string and performs a series of heuristics to turn that string into a unix timestamp.
The line $mysqldate = date( 'Y-m-d H:i:s', $phpdate ) uses that timestamp and PHP's date function to turn that timestamp back into MySQL's standard date format.
(Editor Note: This answer is here because of an original question with confusing wording, and the general Google usefulness this answer provided even if it didnt' directly answer the question that now exists)
To convert a date retrieved from MySQL into the format requested (mm/dd/yy H:M (AM/PM)):
// $datetime is something like: 2014-01-31 13:05:59
$time = strtotime($datetimeFromMysql);
$myFormatForView = date("m/d/y g:i A", $time);
// $myFormatForView is something like: 01/31/14 1:05 PM
Refer to the PHP date formatting options to adjust the format.
If you are using PHP 5, you can also try
$oDate = new DateTime($row->createdate);
$sDate = $oDate->format("Y-m-d H:i:s");
$valid_date = date( 'm/d/y g:i A', strtotime($date));
Reference: http://php.net/manual/en/function.date.php
Finally the right solution for PHP 5.3 and above:
(added optional Timezone to the Example like mentioned in the comments)
without time zone:
$date = \DateTime::createFromFormat('Y-m-d H:i:s', $mysql_source_date);
echo $date->format('m/d/y h:i a');
with time zone:
$date = \DateTime::createFromFormat('Y-m-d H:i:s', $mysql_source_date, new \DateTimeZone('UTC'));
$date->setTimezone(new \DateTimeZone('Europe/Berlin'));
echo $date->format('m/d/y h:i a');
An easier way would be to format the date directly in the MySQL query, instead of PHP. See the MySQL manual entry for DATE_FORMAT.
If you'd rather do it in PHP, then you need the date function, but you'll have to convert your database value into a timestamp first.
Forget all. Just use:
$date = date("Y-m-d H:i:s",strtotime(str_replace('/','-',$date)))
To correctly format a DateTime object in PHP for storing in MySQL use the standardised format that MySQL uses, which is ISO 8601.
PHP has had this format stored as a constant since version 5.1.1, and I highly recommend using it rather than manually typing the string each time.
$dtNow = new DateTime();
$mysqlDateTime = $dtNow->format(DateTime::ISO8601);
This, and a list of other PHP DateTime constants are available at http://php.net/manual/en/class.datetime.php#datetime.constants.types
This should format a field in an SQL query:
SELECT DATE_FORMAT( `fieldname` , '%d-%m-%Y' ) FROM tablename
Use the date function:
<?php
echo date("m/d/y g:i (A)", $DB_Date_Field);
?>
Depending on your MySQL datetime configuration. Typically: 2011-12-31 07:55:13 format. This very simple function should do the magic:
function datetime()
{
return date( 'Y-m-d H:i:s', time());
}
echo datetime(); // display example: 2011-12-31 07:55:13
Or a bit more advance to match the question.
function datetime($date_string = false)
{
if (!$date_string)
{
$date_string = time();
}
return date("Y-m-d H:i:s", strtotime($date_string));
}
SELECT
DATE_FORMAT(demo.dateFrom, '%e.%M.%Y') as dateFrom,
DATE_FORMAT(demo.dateUntil, '%e.%M.%Y') as dateUntil
FROM demo
If you dont want to change every function in your PHP code, to show the expected date format, change it at the source - your database.
It is important to name the rows with the as operator as in the example above (as dateFrom, as dateUntil). The names you write there are the names, the rows will be called in your result.
The output of this example will be
[Day of the month, numeric (0..31)].[Month name (January..December)].[Year, numeric, four digits]
Example: 5.August.2015
Change the dots with the separator of choice and check the DATE_FORMAT(date,format) function for more date formats.
You can also have your query return the time as a Unix timestamp. That would get rid of the need to call strtotime() and make things a bit less intensive on the PHP side...
select UNIX_TIMESTAMP(timsstamp) as unixtime from the_table where id = 1234;
Then in PHP just use the date() function to format it whichever way you'd like.
<?php
echo date('l jS \of F Y h:i:s A', $row->unixtime);
?>
or
<?php
echo date('F j, Y, g:i a', $row->unixtime);
?>
I like this approach as opposed to using MySQL's DATE_FORMAT function, because it allows you to reuse the same query to grab the data and allows you to alter the formatting in PHP.
It's annoying to have two different queries just to change the way the date looks in the UI.
You can have trouble with dates not returned in Unix Timestamp, so this works for me...
return date("F j, Y g:i a", strtotime(substr($datestring, 0, 15)))
This will work...
echo date('m/d/y H:i (A)',strtotime($data_from_mysql));
Using PHP version 4.4.9 & MySQL 5.0, this worked for me:
$oDate = strtotime($row['PubDate']);
$sDate = date("m/d/y",$oDate);
echo $sDate
PubDate is the column in MySQL.
Direct output e.g. in German format:
echo(date('d.m.Y H:i:s', strtotime($row["date_added"])));
$date = "'".date('Y-m-d H:i:s', strtotime(str_replace('-', '/', $_POST['date'])))."'";
i am trying to get the correct time with php
not the one that the user's computer gives is there a function that gives the correct "GMT" time as an example .
PHP gets the server date, not the user computer date.
If you need to get a different date timezone then you need set the timezone to your desired.
See: http://php.net/manual/en/function.date.php
like:
$tz = 'Europe/London';
$timestamp = time();
$dt = new DateTime("now", new DateTimeZone($tz)); //first argument "must" be a string
$dt->setTimestamp($timestamp); //adjust the object to correct timestamp
echo $dt->format('d.m.Y, H:i:s');
If you just want GMT time, you can use gmdate instead of date. For example,
echo date('Y-m-d H:i:s') . "\n";
echo gmdate('Y-m-d H:i:s') . "\n";
Output (for a server in Europe)
2019-02-04 03:34:05
2019-02-04 02:34:05
Demo on 3v4l.org
You will be getting the server time only, not the computer time
$now = new DateTime(null, new DateTimeZone('America/New_York')); //timezone format
echo $now->format("Y-m-d\TH:i:sO"); // Server time
I have checked my mysql system timezone with SELECT ##system_time_zone; and its return EDT in production server. Now I want to generate same timezone's (i.e EDT) current timestamp which is not working. This is what i have tried so far is
date_default_timezone_set('EST');
$ts = strtotime('now');
echo date('Y-m-d H:i:s',$ts);
and
$date = new DateTime(null, new DateTimeZone('EST'));
$ts = $date->getTimestamp();
echo date('Y-m-d H:i:s',$ts);
its output is 2015-09-07 05:38:43 but my mysql date (timestamp) is 2015-09-07 06:39:53 so its not same. (tested by inserting same time)
So how can I get current timestamp based on mysql's system time zone (EDT/EST)?? any help from proessional appricated
The current values of the global and client-specific time zones can be retrieved like this:
mysql> SELECT ##global.time_zone, ##session.time_zone;
And try to use this code to set time zone and Location of time zone
<?php
$date = date_create('2000-01-01', timezone_open('Pacific/Nauru'));
echo date_format($date, 'Y-m-d H:i:sP') . "\n";
date_timezone_set($date, timezone_open('Pacific/Chatham'));
echo date_format($date, 'Y-m-d H:i:sP') . "\n";
?
Note second php code is just an example.
I hope I helped you
I am in need of an easy way to convert a date time stamp to UTC (from whatever timezone the server is in) HOPEFULLY without using any libraries.
Use strtotime to generate a timestamp from the given string (interpreted as local time) and use gmdate to get it as a formatted UTC date back.
Example
As requested, here’s a simple example:
echo gmdate('d.m.Y H:i', strtotime('2012-06-28 23:55'));
Using DateTime:
$given = new DateTime("2014-12-12 14:18:00");
echo $given->format("Y-m-d H:i:s e") . "\n"; // 2014-12-12 14:18:00 Asia/Bangkok
$given->setTimezone(new DateTimeZone("UTC"));
echo $given->format("Y-m-d H:i:s e") . "\n"; // 2014-12-12 07:18:00 UTC
Try the getTimezone and setTimezone, see the example
(But this does use a Class)
UPDATE:
Without any classes you could try something like this:
$the_date = strtotime("2010-01-19 00:00:00");
echo(date_default_timezone_get() . "<br />");
echo(date("Y-d-mTG:i:sz",$the_date) . "<br />");
echo(date_default_timezone_set("UTC") . "<br />");
echo(date("Y-d-mTG:i:sz", $the_date) . "<br />");
NOTE: You might need to set the timezone back to the original as well
Do this way:
gmdate('Y-m-d H:i:s', $timestamp)
or simply
gmdate('Y-m-d H:i:s')
to get "NOW" in UTC.
Check the reference:
http://www.php.net/manual/en/function.gmdate.php
If you have a date in this format YYYY-MM-HH dd:mm:ss,
you can actually trick php by adding a UTC at the end of your "datetime string" and use strtotime to convert it.
date_default_timezone_set('Europe/Stockholm');
print date('Y-m-d H:i:s',strtotime("2009-01-01 12:00"." UTC"))."\n";
print date('Y-m-d H:i:s',strtotime("2009-06-01 12:00"." UTC"))."\n";
This will print this:
2009-01-01 13:00:00
2009-06-01 14:00:00
And as you can see it takes care of the daylight savings time problem as well.
A little strange way to solve it.... :)
Convert local time zone string to UTC string.
e.g. New Zealand Time Zone
$datetime = "2016-02-01 00:00:01";
$given = new DateTime($datetime, new DateTimeZone("Pacific/Auckland"));
$given->setTimezone(new DateTimeZone("UTC"));
$output = $given->format("Y-m-d H:i:s");
echo ($output);
NZDT: UTC+13:00
if $datetime = "2016-02-01 00:00:01", $output = "2016-01-31 11:00:01";
if $datetime = "2016-02-29 23:59:59", $output = "2016-02-29 10:59:59";
NZST: UTC+12:00
if $datetime = "2016-05-01 00:00:01", $output = "2016-04-30 12:00:01";
if $datetime = "2016-05-31 23:59:59", $output = "2016-05-31 11:59:59";
https://en.wikipedia.org/wiki/Time_in_New_Zealand
If you don't mind using PHP's DateTime class, which has been available since PHP 5.2.0, then there are several scenarios that might fit your situation:
If you have a $givenDt DateTime object that you want to convert to UTC then this will convert it to UTC:
$givenDt->setTimezone(new DateTimeZone('UTC'));
If you need the original $givenDt later, you might alternatively want to clone the given DateTime object before conversion of the cloned object:
$utcDt = clone $givenDt;
$utcDt->setTimezone(new DateTimeZone('UTC'));
If you only have a datetime string, e.g. $givenStr = '2018-12-17 10:47:12', then you first create a datetime object, and then convert it. Note this assumes that $givenStr is in PHP's configured timezone.
$utcDt = (new DateTime($givenStr))->setTimezone(new DateTimeZone('UTC'));
If the given datetime string is in some timezone different from the one in your PHP configuration, then create the datetime object by supplying the correct timezone (see the list of timezones PHP supports). In this example we assume the local timezone in Amsterdam:
$givenDt = new DateTime($givenStr, new DateTimeZone('Europe/Amsterdam'));
$givenDt->setTimezone(new DateTimeZone('UTC'));
As strtotime requires specific input format, DateTime::createFromFormat could be used (php 5.3+ is required)
// set timezone to user timezone
date_default_timezone_set($str_user_timezone);
// create date object using any given format
$date = DateTime::createFromFormat($str_user_dateformat, $str_user_datetime);
// convert given datetime to safe format for strtotime
$str_user_datetime = $date->format('Y-m-d H:i:s');
// convert to UTC
$str_UTC_datetime = gmdate($str_server_dateformat, strtotime($str_user_datetime));
// return timezone to server default
date_default_timezone_set($str_server_timezone);
I sometime use this method:
// It is not importnat what timezone your system is set to.
// Get the UTC offset in seconds:
$offset = date("Z");
// Then subtract if from your original timestamp:
$utc_time = date("Y-m-d H:i:s", strtotime($original_time." -".$offset." Seconds"));
Works all MOST of the time.
http://php.net/manual/en/function.strtotime.php or if you need to not use a string but time components instead, then http://us.php.net/manual/en/function.mktime.php
With PHP 5 or superior, you may use datetime::format function (see documentation http://us.php.net/manual/en/datetime.format.php)
echo strftime( '%e %B %Y' ,
date_create_from_format('Y-d-m G:i:s', '2012-04-05 11:55:21')->format('U')
); // 4 May 2012
try
echo date('F d Y', strtotime('2010-01-19 00:00:00'));
will output:
January 19 2010
you should change format time to see other output
General purpose normalisation function to format any timestamp from any timezone to other.
Very useful for storing datetimestamps of users from different timezones in a relational database. For database comparisons store timestamp as UTC and use with gmdate('Y-m-d H:i:s')
/**
* Convert Datetime from any given olsonzone to other.
* #return datetime in user specified format
*/
function datetimeconv($datetime, $from, $to)
{
try {
if ($from['localeFormat'] != 'Y-m-d H:i:s') {
$datetime = DateTime::createFromFormat($from['localeFormat'], $datetime)->format('Y-m-d H:i:s');
}
$datetime = new DateTime($datetime, new DateTimeZone($from['olsonZone']));
$datetime->setTimeZone(new DateTimeZone($to['olsonZone']));
return $datetime->format($to['localeFormat']);
} catch (\Exception $e) {
return null;
}
}
Usage:
$from = ['localeFormat' => "d/m/Y H:i A", 'olsonZone' => 'Asia/Calcutta'];
$to = ['localeFormat' => "Y-m-d H:i:s", 'olsonZone' => 'UTC'];
datetimeconv("14/05/1986 10:45 PM", $from, $to); // returns "1986-05-14 17:15:00"
As an improvement on Phill Pafford's answer (I did not understand his 'Y-d-mTG:i:sz' and he suggested to revert timezone).
So I propose this (I complicated by changing the HMTL format in plain/text...):
<?php
header('content-type: text/plain;');
$my_timestamp = strtotime("2010-01-19 00:00:00");
// stores timezone
$my_timezone = date_default_timezone_get();
echo date(DATE_ATOM, $my_timestamp)."\t ($my_timezone date)\n";
// changes timezone
date_default_timezone_set("UTC");
echo date("Y-m-d\TH:i:s\Z", $my_timestamp)."\t\t (ISO8601 UTC date)\n";
echo date("Y-m-d H:i:s", $my_timestamp)."\t\t (your UTC date)\n";
// reverts change
date_default_timezone_set($my_timezone);
echo date(DATE_ATOM, $my_timestamp)."\t ($my_timezone date is back)\n";
?>
alternatively you can try this:
<?php echo (new DateTime("now", new DateTimeZone('Asia/Singapore')))->format("Y-m-d H:i:s e"); ?>
this will output :
2017-10-25 17:13:20 Asia/Singapore
you can use this inside the value attribute of a text input box if you only want to display a read-only date.
remove the 'e' if you do not wish to show your region/country.
Follow these steps to get UTC time of any timezone set in user's local system (This will be required for web applications to save different timezones to UTC):
Javascript (client-side):
var dateVar = new Date();
var offset = dateVar.getTimezoneOffset();
//getTimezoneOffset - returns the timezone difference between UTC and Local Time
document.cookie = "offset="+offset;
Php (server-side):
public function convert_utc_time($date)
{
$time_difference = isset($_COOKIE['offset'])?$_COOKIE['offset']:'';
if($time_difference != ''){
$time = strtotime($date);
$time = $time + ($time_difference*60); //minutes * 60 seconds
$date = date("Y-m-d H:i:s", $time);
} //on failure of js, default timezone is set as UTC below
return $date;
}
..
..
//in my function
$timezone = 'UTC';
$date = $this->convert_utc_time($post_date); //$post_date('Y-m-d H:i:s')
echo strtotime($date. ' '. $timezone)
