PHP timestamp to HTML 5 input type=datetime element

Question

I have a unix timestamp (int) in PHP. I want to display this value in a nice manner in the HTML5 datetime input element. I would like to be able to have users see this value in a nice presentable manner, as well as edit it. Is there any nice way of doing this, or am I fooling myself and I am going to have to fuss around with lots of string manipulation?

HTML5 Input time is something like this : 1985-04-12T23:20:50.52

You can do that in PHP like this :

echo date("Y-m-d\TH:i:s");

Output

2012-10-02T19:12:49

HTML with Timestamp

<input type="datetime"  value="<?php echo date("Y-m-d\TH:i:s",$timestamp); ?>"/>

That will go in the value attribute of the `` element? Also, I think you mant `.` not `,`, just so it does not confuse anybody else. – thatidiotguy Oct 02 '12 at 17:21

`echo` allows `,` to separate output. – Jason McCreary Oct 02 '12 at 17:23

And i learned something new today. Thank you for being gracious about my supposed correction. – thatidiotguy Oct 02 '12 at 17:35
Not only is `,` allowed with `echo`, but it's faster than `.`. – Zenexer Nov 19 '13 at 01:12
date() is wrong, when you need a specific timezone. use strftime and set timezone. – user706420 Oct 09 '14 at 22:32
This works for me among tens of formation `"Y-m-d\TH:i:s"` – Nam G VU Dec 25 '15 at 05:25
very nice solution when dealing with html5's native datetime – Waqas Shakeel Sep 03 '21 at 13:09

The other examples are both the old way to produce a valid timeStamp format for the TIME element -- the new hotness in php:

<time><?php echo date(DATE_W3C); ?></time>

That will generate a format like:

"2013-05-19T06:40:08+00:00"

The question asks specifically about `input[type=datetime]` *not* `time[datetime]`. Thank you for introducing me to `date()`'s [predefined constants](http://php.net/manual/en/class.datetime.php#datetime.constants.types), though! I will stick to `date('c')` which also results in an identical [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) string as well hehe. – Alastair Feb 21 '14 at 17:43

According to the HTML5 Specification for input type="datetime", it should be as simple as setting the value attribute.

value="<?php echo date('c', $timestamp); ?>"

See PHP's date() function for additional formatters.

Datetime doesn't work for me on chrome, datetime-local allows me to choose date and time from popup.

example

<input type="datetime-local" name="xyz" value="<?php echo date("Y-m-d\TH:i:s",time()); ?>"/>

time() functions is not relevant ,I am using it to make it easy for user to choose from current.. time after or before.
