I've been using setTimeStamp to convert a Unix Timestamp to a datetime in the following way:
$startHireConverted = strtotime($startHire); // converts start hire to time
$endHireConverted = strtotime($endHire); // converts end hire to time
$startdt = new DateTime();
$startdt->setTimeStamp($startHireConverted);
$mysql_startdate = $startdt->format("Y-m-d H:i");
This was working nicely, but recently I've put the website live and the version of PHP can only be 5.2.12 which doesn't support the setTimeStamp method.
I've tried changing setTimeStamp to format which is getting rid of the errors and converting the datetime but it is changing it to the current datetime - 5 hours for some reason rather than the date stored in $startHire.
$startdt->format($startHireConverted);
Any ideas on how to get around this problem?
$startHire starts out as a string version of datetime.
Thankyou
I don't think you need to do the step with unix timestamp at all:
$startdt = new DateTime($startHire);
PHP manual: DateTime::__construct
But that might depend on the format you're getting $startHire in. See Supported Date and Time Formats.

I'm working with Laravel 5.8 and I wanted to show a popup message if the UNIX timestamp of the current date is equal to the defined Unix timestamp of the popup.
So in order to do that, I added this at the Controller:
$date1= $popup->datep; // returns 1636403400
$date1 = Carbon::createFromFormat('Y-m-d H:i:s', $date1);
dd($date1);
But instead of getting the result of $date1, I get this error:
The separation symbol could not be found Data missing
So what's going wrong here? How can I solve this issue?
You are specifying a format that is clearly not an unix timestamp. Use method for the timestamp.
$date = Carbon::createFromTimestamp($popup->datep);
If you want to compare it to be the same date, you should do the following. I don't assume you want to compare it by the hour or second, that those will almost never match.
$date->startOfDay()->eq(now()->startOfDay());
Regarding Carbon Docs:
createFromFormat() is mostly a wrapper for the base php function DateTime::createFromFormat.
which is means that your second parameter must be a valid date/time format, not a timestamp.
The DateTime::create docs:
$datetime
String representing the time.
Instead, you need to use the createFromTimestamp instantiator.
$date1 = Carbon::createFromTimestamp($date1);
I am saving the timestamp in SQL as bigint(20). The number is correct and in android or https://www.epochconverter.com it works fine.
However I am not able to create a date-string based on the timestamp received from database.
First of all, the timestamp seems to come from database as a String, so I can't just say echo date("d.m.Y, $timestamp). The result is the famous 31.12.1969.
So I tried echo date("d.m.Y, strtotime($timestamp)). However, even though strtotime is said to be able to convert almost everything to a timestamp, a simple String containing a timestamp is not possible. Results still remained on the last day of Brian Adams probably favorite year.
Some progress I made by casting the $timestamp to a float value like so: echo date("d.m.Y", floatval($timestamp));. However, now things got really confusing for me. I seemed to have successfully converted my timestamp, however, date() gave me the dates around 02.09.52299.
The timestamps I am using are timestamps of current time, e.g. 1588489252657, which currently leads to the date 23.03.52307.
So all I want is to come to a date based on the timestamp 1588489252657 to see the 03.05.2020 on my screen.
Thanks for any advice!
<?php
$timestamp = 1588489252657; // Timestamp in Milliseconds
$seconds = round($timestamp/1000, 0); // Timestamp Rounded to Seconds
$date = new DateTime(); // Create PHP DateTime Object
$date->setTimestamp($seconds); // Set the Timestamp
echo $date->format('Y-m-d H:i:s'); // Specify the Required Format
The answers are pretty much in the comment sections. But I have shared this answer since this is another approach in OOP fashion. You can leverage the power of PHP's DateTime Class.
PHP Official Documentation For DateTime Class Link Below:
PHP DateTime Class
You have to transform the timestamp to seconds first.
$timestamp = 1588489252657;
$dateInUnixSeconds = round($timestamp / 1000, 0);
$date = \DateTimeImmutable::createFromFormat('U', (string) $dateInUnixSeconds);
echo $date->format('d.m.Y');
PS:
I recommend you to use the \DateTimeImmutable object to avoid mutability problems.

I have been using the following code for a couple of months and it's been working fine, but now seems to have an issue with a certain time or time range.
I have a GPS tracker that sends it's date/time like this:
150102235335
The format is ymdhis
$input_array[6] = 150102235335;
$datetime = DateTime::createFromFormat('ymdhis', $input_array[6]);
$datetime = $datetime->format('Y-m-d h:i:s');
Using that time, php crashes with the following error:
PHP Fatal error: Call to a member function format() on a non-object
It seems that datetime ends up empty.
However, using the time 150103004933 works just fine.
Can anyone see where I have gone wrong here, or is this a bug?
Is there a better way to accomplish my date conversion?
I am using PHP 5.4.35
h is 12-hour format; and therefore 23 hours is invalid. Only values in the range 00-11 would be valid.
H is 24-hour format
I've been struggling to get an exact answer for this question. There are many that are close to what I'm wanting but seem to still be just off. The application of this is to ensure that a booking can't be made for a past date.
I have a form which has an input for time & another for date. Firstly, I wan't to take both of these inputs & convert them to a timestamp.
This code returns nothing
$time_date = sprintf("%s %s", $pDate, $pTime);
$objDate = DateTime::createFromFormat('H:ia d/m/Y', $time_date);
$stamp = $objDate->getTimestamp();
echo $stamp;
So I've have tried using something like this
$pDate = $_POST['pDate'];
$pTime = $_POST['pTime'];
$full_date = $pDate . ' ' . $pTime;
$timestamp = strtotime($full_date);
echo $timestamp;
But for some reason it is returning an incorrect timestamp. (i've been using an online converter) 02/06/2014 as date & 12:23am as time, is not 1401625380. This according to the converter is Sun, 01 Jun 2014 12:23:00 GMT.
Does someone have working code for returning a timestamp of both time & date inputs?
Secondly I want to compare this timestamp with a specified one & check to see if it is greater than. I've created a timestamp for my timezone with this
$date = new DateTime(null, new DateTimeZone('Pacific/Auckland'));
$cDate = $date->getTimestamp();
echo $cDate;
and will simply have an if statement which compares the two and echos the appropriate message.
I feel as though there are multiple question on here that are ALMOST what I'm wanting to achieve but I can't manage to get them working. Apologies for the near duplicate.
Note: I'm using ajax to post form data (if this could possibly interfere).
Your second code snipped is correct. Assuming it's in datetime format (Y-m-d H:i:s).
From php manual about strtotime():
Each parameter of this function uses the default time zone unless a time zone is specified in that parameter.
Check your PHP default time zone with date_default_timezone_get() function.
To compare two dates, be sure they both are in same time zones.
For datetime inputs I personally use jQuery UI timepicker addon.
you receiving the time and date in string format - so i don't believe the ajax can interfere.
as for your question:
first of all - find out what is the locale timezone of your server. you can do it by this function: date_default_timezone_get.
if the answer doesn't suit you - you can use its "sister": date_default_timezone_set, and change it to whatever value you need (like 'Pacific/Auckland' - see the documentation there). it is also recommended to return it to the original value after you finish your stuff.
i believe fixing your locale timezone will solve your issue.
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)
