I need to convert this time to UTC+00 timezone time. It gives me a date with timezone depending from where user is in RFC3339 format. So it looks like this


I need to use the +02 timezone and correctly calculate the date. So my idea is: Do I just check what is the last 00:00 and - or + days from the date? Or is there actually functions to use from php side like time_convert( ) etc..?

I've made this, how ever I am not sure if its correct way of doing it.

$date = '2000-01-01 00:00:00+02:00';
$date_date = substr($date, 0, 19);
$add_hours = substr($date, 19, 22)*3600;
$add_mins = substr($date, 23, 25)*60;
$add_secs = $add_hours+$add_mins;
$date = date('Y-m-d H:m:i', strtotime($date_date)+$add_secs);

gmdate is intended to format GMT(=UTC) output. See PHP: gmdate - Manual

You may get the result you want by using :

$date = strtotime("2000-01-01 00:00:00+02:00");
$utc = gmdate("Y-m-d H:i:sP", $date);

where P is the offset with GMT.

foo must be an RFC 3339 date-time, Change the date-time format to comply with RFC 3339. errors include using a space to separate the data and time, or omitting the time zone information. We finally decide to use the RFC 3339 as the standard for the date-time format. Means, both backend and frontend will use this format to communicate about the DateTime format. And also, we agreed

You can probably use DateTime with DateTimeZone to get what you're after.

Here's a quick example of how you may use it.


$date = new DateTime('now', new DateTimeZone('UTC'));
$date->setTimezone(new DateTimeZone('America/Los_Angeles'));

echo $date->format('Y-m-d H:i:s'); // Converted to LA timezone.

You may get the result you want by using : RFC 3339 Date and Time on the Internet: Timestamps July 2002 4.2.Local Offsets The offset between local time and UTC is often useful information. For example, in electronic mail (RFC2822, [IMAIL-UPDATE]) the local offset provides a useful heuristic to determine the probability of a prompt response.

You can do it so simple like:

$date = new DateTime('now')
echo $date;

Output: 2018-11-12T15:55:00+00:00

RFC 3339 - Date and Time on the Internet: Timestamps, (This example shows negative offsets handled by adding the absolute value of the offset.) NOTE: Following ISO 8601, numeric offsets represent only time zones​  The strftime call you give in the first section does not produce a valid RFC3339 string. In RFC3339, the time zone needs to be formatted with a colon. For your example to be valid, it would have to look like this: "2018-02-13T12:32:52-06:00" – Luchs Nov 21 '18 at 8:25

What is a standard command for printing a date in RFC-3339 format , My timezone offset is currently -08:00 so the simplest form of this command should print the current time as 2013-09-05T14:58:33.102-08:00 . share. The date command doesn't offer such thing, which is kind of sad since RFC-3339 is the modern, widespread, sane format used everywhere (except in email which is neither modern nor sane). My timezone
