Is there a way for me to tell the strtotime() function not to change the time I give it into BST? i.e. if do
date('g.ia', strtotime("2014-06-25T19:30"))
I want to get 7:30pm, just as if I entered
date('g.ia', strtotime("2014-06-25T19:30"))
(The first one currently returns 6:30pm)
I'm aware I could just write a manual check for the day/month and add an hour if necessary, or just parse the time myself from the string, but both solutions sound a bit messy (I'll have to do this in quite a few places).
Sorry if there's something obvious I'm missing, pretty new to php
Function date() will format time based on your timezone setting. Said that, your example doesn't make sense since strtotime() will use current timezone setting to convert input to unix timestamp, and then function date() will use again that timezone setting to format timestamp back. You must be changing timezone setting between strtotime() and date() function calls, like this demo.
You can simply use DateTime extension, where you implicitly tell in what timezone is your time:
$dt = new DateTime('2014-06-25T19:30', new DateTimezone('Europe/London'));
echo $dt->format('g.ia');

I need to display and handle UTC dates in the following format:
2013-06-28T22:15:00Z
As this format is part of the ISO8601 standard I have no trouble creating DateTime objects from strings like the one above. However I can't find a clean way (meaning no string manipulations like substr and replace, etc.) to present my DateTime object in the desired format. I tried to tweak the server and php datetime settings, with little success. I always get:
$date->format(DateTime::ISO8601); // gives 2013-06-28T22:15:00+00:00
Is there any date format or configuration setting that will give me the desired string? Or I'll have to append the 'Z' manually to a custom time format?
No, there is no special constant for the desired format. I would use:
$date->format('Y-m-d\TH:i:s\Z');
But you will have to make sure that the times you are using are really UTC to avoid interpretation errors in your application.
If you are using Carbon then the method is:
echo $dt->toIso8601ZuluString();
// 2019-02-01T03:45:27Z
In PHP 8 the format character p was added:
$timestamp = new DateTimeImmutable('2013-06-28T22:15:00Z');
echo $timestamp->format('Y-m-d\TH:i:sp');
// 2013-06-28T22:15:00Z
In order to get the UTC date in the desired format, you can use something like this:
gmdate('Y-m-d\TH:i:s\Z', $date->format('U'));
To do this with the object-oriented style date object you need to first set the timezone to UTC, and then output the date:
function dateTo8601Zulu(\DateTimeInterface $date):string {
return (clone $date)
->setTimezone(new \DateTimeZone('UTC'))
->format('Y-m-d\TH:i:s\Z');
}
Edit: clone object before changing timezone.
Since PHP 7.2 DateTimeInterface::ATOM was introduced in favor of DateTimeInterface::ISO8601, although it still lives on for backward compatability reasons.
Usage
$dateTimeObject->format(DateTimeInterface::ATOM)
I need to convert a specific date format into local time (Europe/Sarajevo), I have the time in this format 2013-02-17T15:00:00Z which I don't really understand and this is why I don't know how to convert it to the Europe/Sarajevo time, who knows maybe it is already Sarajevo time, I don't know...
OK I can parse it and remove the T and Z and get a time but these letters mean something, probably they affect the result time...
The result time is for example 2013-02-17 18:00:00, probably there will be a difference due to the letters T and Z which are probably time offset.
Use DateTime. It's much better for working with timezones:
$datetime = new DateTime('2013-02-17T15:00:00Z');
$datetime->setTimeZone(new DateTimeZone('Europe/Sarajevo'));
echo $datetime->format('c');

You can use php date function like this
$date = '2013-02-17T15:00:00Z';
echo date('Y-m-d H:i:s',strtotime($date));
See the Manual
How can I convert string "M-d-Y::H:i:s" to unix timestamp in php. I just realized manipulating date and time must be the most time consuming entity in any programming language.
Trivial Question: Why do you think there isn't any universal date time format. Why are there so many variations of same data? AArrhh.
The OOP way (requires PHP >= 5.3.0):
$dt = DateTime::createFromFormat("M-d-Y::H:i:s", $input);
$ts = $dt->getTimestamp();
You should of course check the return value of createFromFormat (it's false if an error occurs) but you should also definitely check DateTime::getLastErrors(); otherwise you might be surprised if e.g. your input has a day of "Jan 32". See my answer here for more info.
i have this issue service unavailable (with message) ResponseText: Error: Call to a member function getTimestamp() on boolean How to fixed this issue.
I display the date or the time on my website a lot and I'm thinking about writing a function to parse a PostgreSQL timestamp.
The timestamp is in the format: Y-m-d H:i:s.u. E.g. 2011-04-08 23:00:56.544.
I'm thinking about something like this:
function parse_timestamp($timestamp, $format = 'd-m-Y')
{
// parse the timestamp
return $formatted_timestamp;
}
However I am wondering whether this can also be achieved without writing a parser for it myself (with the use of some PHP function).
function parse_timestamp($timestamp, $format = 'd-m-Y')
{
return date($format, strtotime($timestamp));
}
Don't forget to set timezone before, e.g.
date_default_timezone_set('UTC');
Or in your case, I guess 'Europe/Amsterdam'.
You can always get PHP timestamp of this format Y-m-d H:i:s.u using strtotime(). Then, using date() you can export time in your own format. Both functions depend of time zone set.
strtotime is perfectly capable of parsing that time string, then just reformat it with date:
echo date('d-m-Y', strtotime('2011-04-08 23:00:56.544')); // 08-04-2011
For those using DateTime class:
DateTime::createFromFormat('Y-m-d H:i:s.u', $yourTime);
If the database isn't giving you what you want, change it. PostgreSQL can also format dates and times.
select to_char(timestamp '2011-03-04 07:04:00', 'DD-MM-YYYY');
04-03-2011
But that's risky in international contexts, like the web. Different locales expect different ordering of elements. (Does "04-03" mean 03-April or 04-March?) This expression is easier to understand, and it uses locale-specific abbreviations for the months.
select to_char(timestamp '2011-03-04 07:04:00', 'DD-Mon-YYYY');
04-Mar-2011
Take a look at the strptime function - it can parse many time formats.
To change 2009-12-09 13:32:15 to 09/12/2009
here:
echo date("d/m/Y", strtotime('2009-12-09 13:32:15'))
You can use strtotime to get the timestamp of the first date, and date to convert it to a string using the format you want.
$timestamp = strtotime('2009-12-09 13:32:15');
echo date('d/m/Y', $timestamp);
And you'll get :
09/12/2009
[edit 2012-05-19] Note that strtotime() suffers a couple of possibly important limitations:
The format of the date must be YYYY-MM-DD; it might work in some other cases, but not always !
Also, working with UNIX Timestamps, as done with date() and strtotime() means you'll only be able to work with dates between 1970 and 2038 (possibly a wider range, depending on your system -- but not and illimited one anyway)
Working with the DateTime class is often a far better alternative:
You can use either DateTime::__construct() or DateTime::createFromFormat() to create a DateTime object -- the second one is only available with PHP >= 5.3, but allows you to specify the date's format, which can prove useful,
And you can use the DateTime::format() method to convert that object to any date format you might want to work with.
Using the date() method.
print date("d/m/Y", strtotime("2009-12-09 13:32:15"));
$long_date = '2009-12-09 13:32:15';
$epoch_date = strtotime($long_date);
$short_date = date('m/d/Y', $epoch_date);
The above is not the shortest way of doing it, but having the long date as an epoch timestamp ensures that you can reuse the original long date to get other date format outputs, like if you wanted to go back and have just the time somewhere else.
