strtotime is being calculated from 1970-01-01 (UTC) and date is using my timezone i.e America/New_York
A simple example:
Where timestamp is 0:
var_dump(date('Y-m-d h:i:s', 0));
prints: 1969-12-31 07:00:00
Where it should return 0, it returns
var_dump(strtotime('1969-12-31 07:00:00'));
-43200
Now, obviously, I could add the timezone to the date i.e
strtotime($date . ' -5')
and it'd work.
But, I'm using the strtotime function everywhere.
I tried playing with the _$ENV['TZ'] and the date_timestamp_get();
But I can't sync them.
I also modified the date.timezone in php.ini to America/New_York and still nothing.
Finally, forcing the timezone using date_timestamp_set('UTC'), works fine and both dates are synced. But, I need the timezone from the server.
Please advise, I'm out of ideas
var_dump(date('Y-m-d H:i:s', 0));
h != H in date. It is 7pm, and you're trying to get the time from 1969-12-31 07:00:00am after.

I'm fairly new to PHP so forgive me if this is a stupid mistake that I haven't spotted
I've run into a problem where in our current system where we currently used strtotime and it was returning our date an hour ahead than it actually was set. E.g 1:15pm became 2:15pm when I set the timezone to be European rather than GMT.
I read that strotime had this problem but I can't get it to observe a different timezone if I try and set it.
So I tried working with PHPs DateTime instead.
The user enters the time and they select it as 1:15PM however we want to store it as 13:15. So I did this:
$t = DateTime::createFromFormat('h:i A', $venue['startTime']);
$t_24 = $t->format('H:i:s');
Then I try and create my Date object
$d = DateTime::createFromFormat('d-m-Y H:i:s', $venue['startDay'] . ' ' . $t_24);
$d->setTimezone(new DateTimeZone('America/New_York'));
echo ' ' . $d->getTimestamp();
Trying to set the timezone after the object is set because apparently it doesn't work if you add the timezone as the third argument in createFromFormat
My computers time is currently observing European time currently GMT+1 because we're observing daylight savings time in the UK, I select the time set on the through our system as 1:15pm and because I've set the timezone I expect the timestamp outputted equivalent to 7:15am as it's six hours behind European time, however when I convert the timestamp 1500639300 it's still equal to 2:15 PM. Probably done something stupid but can't quite figure out what? Any help would be appreciated :)
Timestamps have no time zone - they are always in UTC time. If you want to save timezone related data use another format! For example save in H:i:s, as you need it.
you can use gmdate() Function for this
<?php $current_time = gmdate('Y-m-d H:i:s'); ?>
http://php.net/manual/en/function.gmdate.php
This is the coding and it is echoing with the right format but the fact that the date is wrong when it prints out.
Output: 31 Dec 1969 19:33
Database Timestamp 2016-05-20 21:53:17
<?php
date_default_timezone_set('ECT');
$timestamp = 1456778973;
echo date('d M Y H:i',$row['timestamp']);
?>
and i have tried doing the date in different ways and still the same result
In the code sample you posted, $row['timestamp'] has not been set, so the date is constructed with timestamp 0, also known as epoch, or the date that is being echoed.
If you change it as follows, it should work fine:
<?php
date_default_timezone_set('ECT');
$timestamp = 1456778973;
echo date('d M Y H:i', $timestamp); ?>
Side note:
Time zone ECT is not a valid time zone code in PHP. If I assume correctly that you mean european central time, you would have to specify CET instead.
ECT doesn't exist as a valid TimeZone, did you mean CET perhaps?
The correct way to do this is using the DateTime class, i.e.:
$date = new DateTime();
$date->setTimestamp(1456778973);
$tz = new DateTimeZone("America/Denver");
$date->setTimezone($tz);
echo $date->format('d M Y H:i');
PHPFiddle Demo
Note:
Dates should always be stored in DB as UTC (timestamp aka unix time), then you can add or subtract the timezone offset using the DateTime class.
Would you know what the offset would be for mountain standard time?
Mountain Time: America/Denver
Mountain Time (no DST): America/Phoenix
List of Supported Timezones
I am trying convert a utc time stored date to another time zone but i cant seem to get it right.
I have a time :
date1 = new DateTime('first day of the month');
date1.setTime(0,0,0); // Since using the first day of the month seems return the current time with different date
The default DateTime timezone is in UTC. The time i want to make reference is in 'Europe/Amsterdam' timezone. Any way i cant get the time in 'Europe/Amsterdam' timezone to be equivalent to the first day of the month time in UTC? (Uh, sorry my question was confusing.. let me just give an example to be clear). Im trying to query from a db.
If UTC date time is June 01, 2013. 00:00:00
I want to get get May 29, 2013 19:55:00.
I tried getting the difference between the two declared times with different timezones to get the time that i wanted but it seems it didnt work :(
My Edit/ Clarification:
If use this code:
$date1 = new DateTime('first day of the month');
$date1.setTime(0,0,0);
print_r($date1->format('Y-m-d H:i:s'));
I would get:
2013-06-01 00:00:00
Then if i use timezone:
$date1->setTimeZone(new DateTimeZone('Europe/Amsterdame'));
print_r($date1->format('Y-m-d H:i:s'));
I would get: (This is just a sample output):
2013-06-01 03:00:00
Because of time difference. Want i want to get is like the reverse: I want to get the datetime that when converted 'UTC' timezone i would get this: 06-01-2013 00:00:00 time. So my preffered output is : 2013-05-29 21:00:00 ...
You can do in an OOP way like so.
$date = new DateTime('2000-01-01 00:00:00', new DateTimeZone('Europe/Amsterdam'));
echo $date->format('Y-m-d H:i:s P') . "\n";
To set the default date in PHP, you can either set it in your ini file or in a PHP file like so:
date_default_timezone_set('Europe/Amsterdam');
Then to format the date, refer to http://www.php.net/manual/en/function.date.php for formatting.
In your case this would be:
date('j M Y' time());
Where j = day, M = month and Y = year.
I'm changing the date format and it shows me wrong format
echo $punch_in_time;
// Prints 2013-09-09 11:40:00
echo $new_date = gmdate('D, M-d-Y h:i a',strtotime($punch_in_time));
// Prints Mon, Sep-09-2013 09:40 am (Notice the wrong time)
I also tried to set the time zone before displaying the time, but no effect.
I don't know why this is happening, it must show my time as Mon, Sep-09-2013 11:40 am instead of Mon, Sep-09-2013 09:40 am.
besure to read the description/manual before you use a function.
it says "Format a GMT/UTC date/time" in the description of gmdate(), which means it is assuming the date you entered is in the local time zone (judging from the time difference GMT+2 ?) gmdate then convert it to a date format in GMT+0 time zone.
to make sure the timezone* is consistance between both input and output, use date() instead.
*this will convert the datetime to your local timezone, which might not be what you need.
echo $new_date = date('D, M-d-Y h:i a',strtotime($punch_in_time));
gmdate() identical to the date() function except that the time returned is Greenwich Mean Time
use this instead
echo $new_date = date('D, M-d-Y h:i a',strtotime($punch_in_time));
I have a simple date time in the format 10/20 4:30PM. I want it to display in the format
10/24 1:30PM -007. I am saying date('Y-m-d H:i:sT', $time_recieved) assuming T is for timezone. But It is still not giving the time zone. What might be the reason? Is there any other format I am missing?
What you want is O not T I believe.
Check the PHP date page for all the format listings possible.
http://php.net/manual/en/function.date.php
You can have a look at the official manual of PHP : date ();
http://www.php.net/manual/en/function.date.php
I tested that and I used on my server with :
$time = time();
echo date('Y-m-d H:i:s T', $time);
it shows the timezone perfectly. Check $time_received, it might be an erroneous number, try with local time with time´() function to ensure that it's OK.
Good luck
