Installation
------------

[](#installation)

UTCDateTime is installed via composer. Call `composer require utcdatetime/utcdatetime` from the commandline in your project.

Alternatively you can include the following line in your `composer.json` inside the `require`-section:

```
"utcdatetime/utcdatetime" : "stable"

```

Usage
-----

[](#usage)

Use the UTCDateTime- or UTCDateTimeImmutable-Object just like PHPs own DateTime-Objects. You do not have to rewrite any productive code. Just add `use UTCDateTime/DateTime` resp. `use UTCDateTime\DateTimeimmutable` to the `use`-section of your PHP-file. That will cause PHP to use the UTCDateTime-Objects instead of the PHP-Internal DateTime-Objects.

Calls to `setTimeZone` will be ignored, all other calls will be executed just as before. The only difference will be, that no matter what you put into the DateTime-Objects, it will always contain the UTC-representation of your date. And there is no way to change that.

So any Datetime-data will always be correctly converted to UTC and you can then work with that like so:

```
use UTCDateTime\DateTime;
$date = new DateTime('2014-11-03 12:34:56', new DateTimeZone('Europe/Berlin'));
echo $date->format(DateTime::RFC3339);
// 2014-11-03T10:34:56+00:00

```

Additional Constants
--------------------

[](#additional-constants)

This package also introduce some more formating-constants.

Those include:

- DateTime::RFC7231 for formatting date according to RFC 7231
- DateTime::PDF for formatting dates for internal PDF-Storage
