Kibatic Timezone Bundle

This bundle is used to manage the display of a \DateTimeInterface in the right timezone.

The common case is a project with all the \DateTimeInterface objects are in UTC (in the DB, in PHP, ...) but the user can change the timezone in his preferences in order to display the dates with its own timezone.

Quick start

installation

composer require kibatic/timezone-bundle

in config.yml

kibatic_timezone:
    default_display_timezone: "Europe/Paris"    # mandatory
    timezone_provider: "App\\Timezone\\MyTimezoneProvider"   # optional

in php

/** @var \DateTimeInterface $date */
$date = new \DateTimeImmutable();

$tzAdjuster = $container->get('kibatic_timezone.adjuster');
$dateTimeImmutable = $tzAdjuster->asDateTimeImmutable($date);
$dateTime = $tzAdjuster->asDateTime($date);

Convert \DateTime to a given timezone with AdjusterUtil

$date = new \DateTime('2019-10-03T15:28:06.256+02:00');
$dateModified = AdjusterUtil::changeTimezone($date, new \DateTimeZone('GMT+0'));

Format datetime with timezone in twig

in twig the syntax of tzdate is exactly the same as the twig date filter. (it calls the default date filter. The only difference is that the timezone argument is set to false by default)

{{ date | tzdate }}
{{ date | tzdate('Y/m/d') }}

Format Datetime in twig with localization (intl)

You can use the new twig : tz_format_datetime filter. It has the same interface than the format_datetime filter from twig/extra-bundle, but with a $timezone to false by default.

{{ date | tz_format_datetime('short', 'short') }}
{{ date | tz_format_datetime('long', 'long') }}
{{ date | tz_format_datetime }}

Deprecated Localized date

You can use the new twig : tzlocalizeddate filter. It has the same interface than the localizeddate filter from twig-extension intl, but with a $timezone to false by default.

{{ date | tzlocalizeddate('short', 'short') }}
{{ date | tzlocalizeddate('long', 'long') }}
{{ date | tzlocalizeddate }}

Timezone Provider

A timezone Provider is a service that implements TimezoneProviderInterface.

It's a service that is used to know the current timezone to display (for a webpage, an API, in a command, for an export,...)

It implements TimezoneProviderInterface

The adjuster as twig global variable

If needed, you can add the adjuster as a twig global variable :

in config/packages/twig.yaml, you can add

twig:
  globals:
    timezoneAdjuster: '@kibatic_timezone.adjuster'

and then in any twig you can use the adjuster

<div>Timezone : {{ timezoneAdjuster.displayTimezone().name }}</div>

{# convertir un datetime en datetime avec la bone timezone #}
{{ timezoneAdjuster.asDateTime(date) }}
