The $bet_closing is set to this in the WordPress admin: November 9, 2011 6:59AM GMT
Which is 12:01 am PST (California Time) on November 9th. But I want to be able to add another option in the admin so they can select a timezone based on UTC. In my own state it's UTC -7. I tried this "November 9, 2011 6:59AM GMT -0700" but no go.
// Auto Close Bet
$now = time();
$bet_closing = strtotime(get_option('cp_gamble1_endtime'));
if ($bet_closing > $now) { // Betting Open!
$output .= 'On';
$cp_gamble1_onoff = true;
update_option('cp_gamble1_onoff', $cp_gamble1_onoff);
} else {
$cp_gamble1_onoff = false;
update_option('cp_gamble1_onoff', $cp_gamble1_onoff);
$output .= 'Over';
}
I'm sure there is a better way to do this. If there is I'm all ears :)
Just tested this (I put the command and the next line gives the result):
var_dump(strtotime("November 9, 2011 6:59AM GMT"));
int(1320821940)
the same as:
var_dump(strtotime("November 9, 2011 6:59AM GMT -0700"));
int(1320821940)
But without GMT works well:
var_dump(strtotime("November 9, 2011 6:59AM -0700"));
int(1320847140)
You can use date_default_timezone_set() function to set timezone before calling strtotime() function

I have a problem. I want to convert this DateTime: 2018-10-28 02:00:00 to a TimeStamp. Now the TimeStamp I am looking for is: 1540684800, but with my code I get this TimeStamp: 1540688400. I know it has something to do with my TimeZone, but I don't know how I can fix this.
I live in the Netherlands in Amsterdam.
Here is my code:
$LoopDateTime = "2018-10-28 02:00:00";
$search_key = (strtotime($LoopDateTime)*1000);
Can someone help me?
The time zone identifier for Amsterdam is Europe/Amsterdam and 1540688400 is the correct timestamp. There's surely an online tool to check but you can also verify it from PHP itself:
$date = new DateTime("#1540688400");
$date->setDateTimeZone(new DateTimeZone('Europe/Amsterdam'));
echo $date->format('r'); // Sun, 28 Oct 2018 02:00:00 +0100
However your code is not robust because depends on the configured timezone. You can just set it explicitly in a number of ways, e.g.:
$LoopDateTime = "2018-10-28 02:00:00";
$search_key = strtotime($LoopDateTime . ' Europe/Amsterdam') * 1000;
var_dump($search_key); // int(1540688400000)
Or:
date_default_timezone_set('Europe/Amsterdam');
$LoopDateTime = "2018-10-28 02:00:00";
$search_key = strtotime($LoopDateTime) * 1000;
var_dump($search_key); // int(1540688400000)
P.S. If I'm not wrong Sunday 28 Oct 2018 02:00:00 +0100 is the exact moment when most Europe has just switched from CEST (+0200) to CET (+0100).
Here I select a date: 21 Feb, 2019
$ri_arrival_date = $_POST["ri_arrival_date"];
$arvl_date = strtotime($ri_arrival_date);
$arvl_date = date('d M,Y',$arvl_date);
$check_in_date = $ri_arrival_date;
$datetime = new DateTime($arvl_date);
$datetime->setTime(0, 0, 0);
$arvl_date = $datetime->getTimestamp();
echo $arvl_date;
echo result is 1550703600 (February 21, 2019 5:00:00 AM) But in my database it saved by 1550685600 (February 21, 2019 12:00:00 AM) Two value is different.
I want to get 1550685600 the database DateTime value. But it couldn't match.
I just use $datetime->setTime(-5, 0, 0); to fix this problem.
Verify the server timezone and the mysql timezone if is on a different server.
In all my php I set my timezone based on my location defined instead of the one of the server. This will eliminate the confusion If host my server on another timezone. And also can be expanded/upgrade to accept the user timezone if needed.
<?php
date_default_timezone_set('America/New_York');
?>
I am building a booking system in php that offers session times for people to book outdoor activities.
In the summer months, there is an extra session available at the end of the day, because of Daylight Savings, there is an extra hour in the evenings.
Year Clocks go forward Clocks go back
2014 30 March 26 October
2015 29 March 25 October
2016 27 March 30 October
2017 27 March 30 October
2018 25 March 28 October
I am using this...
$todaysDate = strtotime(date("Y-m-d"));
$bstBegin = strtotime("2015-03-29");
$bstEnd = strtotime("2015-10-25");
if($todaysDate > $bstBegin && $todaysDate > $bstEnd)
{
echo "<option value="evening">Evening Session</option>";
}
I only need to show this extra option in the select list between these dates. Is this something I will need to set manually from year to year, or is there a PHP date variable that knows the days the clocks change?
$today = strtotime(date("Y-m-d"));
if (date('I', $today)) {
echo "We're in BST!";
} else {
echo "We're not in BST!";
}
or use the DateTime object equivalent, which maintains details of all the transition dates globally
I work normally with the DateTime functions and like it very much. You have a lot of possibilities to modify a date.
But in your case you can concat the actual year to your string.
$todaysDate = strtotime(date("Y-m-d"));
$bstBegin = strtotime(date('Y')."-03-29");
$bstEnd = strtotime(date('Y')."-10-25");
I hope i have understood your problem correctly.
I have found this online very good ref : https://gist.github.com/aromig/56376f76d4fb653ba83e
public function is_BST() {
$theTime = time();
$tz = new DateTimeZone('Europe/London');
$transition = $tz->getTransitions($theTime, $theTime);
$abbr = $transition[0]['abbr'];
return $abbr == 'BST' ? true : false; }
Good !
I am having some difficulties with extracting data from a date. The thing is that I get a number from an undocumented API.
"created": 734394
"last_chapter_date": 734883
I tried dividing it by 365,242 days (exact amount of days a year)
2010,705231052289
So apparently these are the number of days passed since 0.0.0000
I am currently trying something like that:
http://jsfiddle.net/LRUy5/4/
function zero21970(nDays) {
// 0 70 2013
// |-----|-----|
// 0 to date
var dateMils = nDays*24*60*60*100;
// 0 to 1970
zeroTo1970 = (1970*365.242)*24*60*60*100;
//subtract time from 0-1970 from the time 0-date
//to cut out the part from 1970-today
return new Date(dateMils-zeroTo1970);
}
//http://www.mangaeden.com/api/manga/4e70e9f6c092255ef7004344/
zero21970(734394) //-> Jan 26 1974
I need to save it in a database and work with it via php or javascript..
Does anyone recognize this kind of format or do you know a convenient way of formatting it?
Edit: I should add that the last chapter came out around 15.01.2013.. just to have something to grab.
Updated version:
I guess if the last chapter was from 2013, then the value is a number of days from 01.01.0001. So we can update the initial date as well as change setHours to setDate method for more accuracy:
var date = new Date("0001");
date.setDate(734883);
date.toGMTString(); // "Tue, 15 Jan 2013 00:00:00 GMT"
DEMO: http://jsfiddle.net/LRUy5/6/
Old version:
I found one solution that successfully works at my computer:
var date = new Date("0000");
date.setHours(734394 * 24);
date.toGMTString(); // "Mon, 13 Sep 2010 21:00:00 GMT"
DEMO: http://jsfiddle.net/LRUy5/5/
If you're using PHP, then you should replace
return new Date(dateMils-zeroTo1970);
with
return date('Y-m-d', (dateMils-zeroTo1970));
Do you know how I can convert this to a strtotime, or a similar type of value to pass into the DateTime object?
The date I have:
Mon, 12 Dec 2011 21:17:52 +0000
What I've tried:
$time = substr($item->pubDate, -14);
$date = substr($item->pubDate, 0, strlen($time));
$dtm = new DateTime(strtotime($time));
$dtm->setTimezone(new DateTimeZone(ADMIN_TIMEZONE));
$date = $dtm->format('D, M dS');
$time = $dtm->format('g:i a');
The above is not correct. If I loop through a lot of different dates its all the same date.
You don't need to turn the string into a timestamp in order to create the DateTime object (in fact, its constructor doesn't even allow you to do this, as you can tell). You can simply feed your date string into the DateTime constructor as-is:
// Assuming $item->pubDate is "Mon, 12 Dec 2011 21:17:52 +0000"
$dt = new DateTime($item->pubDate);
That being said, if you do have a timestamp that you wish to use instead of a string, you can do so using DateTime::setTimestamp():
$timestamp = strtotime('Mon, 12 Dec 2011 21:17:52 +0000');
$dt = new DateTime();
$dt->setTimestamp($timestamp);
Edit (2014-05-07):
I actually wasn't aware of this at the time, but the DateTime constructor does support creating instances directly from timestamps. According to this documentation, all you need to do is prepend the timestamp with an # character:
$timestamp = strtotime('Mon, 12 Dec 2011 21:17:52 +0000');
$dt = new DateTime('#' . $timestamp);
While #drrcknlsn is correct to assert there are multiple ways to convert a time string to a datatime, it's important to realize that these different ways don't deal with timezones in the same way.
Option 1 : DateTime('#' . $timestamp)
Consider the following code :
date_format(date_create('#'. strtotime('Mon, 12 Dec 2011 21:17:52 +0800')), 'c');
The strtotime bit eliminates the time zone information, and the date_create function assumes GMT.
As such, the output will be the following, no matter which server I run it on :
2011-12-12T13:17:52+00:00
Option 2 : date_create()->setTimestamp($timestamp)
Consider the following code :
date_format(date_create()->setTimestamp(strtotime('Mon, 12 Dec 2011 21:17:52 +0800')), 'c');
You might expect this to produce the same output. However, if I execute this code from a Belgian server, I get the following output :
2011-12-12T14:17:52+01:00
Unlike the date_create function, the setTimestamp method assumes the time zone of the server (CET in my case) rather than GMT.
Explicitly setting your time zone
If you want to make sure your output matches the time zone of your input, it's best to set it explicitly.
Consider the following code :
date_format(date_create('#'. strtotime('Mon, 12 Dec 2011 21:17:52 +0800'))->setTimezone(new DateTimeZone('Asia/Hong_Kong')), 'c')
Now, also consider the following code :
date_format(date_create()->setTimestamp(strtotime('Mon, 12 Dec 2011 21:17:52 +0800'))->setTimezone(new DateTimeZone('Asia/Hong_Kong')), 'c')
Because we explicitly set the time zone of the output to match that of the input, both will create the same (correct) output :
2011-12-12T21:17:52+08:00
Probably the simplest solution is just:
DateTime::createFromFormat('U', $timeStamp);
Where 'U' means Unix epoch. See docs: http://php.net/manual/en/datetime.createfromformat.php
This is my solution:
function changeDateTimezone($date, $from='UTC', $to='Asia/Tehran', $targetFormat="Y-m-d H:i:s") {
$date = new DateTime($date, new DateTimeZone($from));
$date->setTimeZone(new DateTimeZone($to));
return $date->format($targetFormat);
}
