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 <input type="datetime" ... /> element? Also, I think you mant . not ,, just so it does not confuse anybody else.
echo allows , to separate output.
And i learned something new today. Thank you for being gracious about my supposed correction.
Not only is , allowed with echo, but it's faster than ..
date() is wrong, when you need a specific timezone. use strftime and set timezone.

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, though! I will stick to date('c') which also results in an identical ISO 8601 string as well hehe.

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.
