Usage

<?php

// Internally uses SystemClock::new(new DateTimeZone(date_default_timezone_get()));

date_default_timezone_set('America/Los_Angeles');
$systemClock = SystemClock::new();
$systemClock->now(); // DateTimeImmutable
$systemClock->now()->getTimezone()->getName(); // America/Los_Angeles

date_default_timezone_set('America/New_York');
$systemClock = SystemClock::new();
$systemClock->now(); // DateTimeImmutable
$systemClock->now()->getTimezone()->getName(); // America/New_York

$localizedClock = LocalizedClock::new();
$localizedClock->now(); // DateTimeImmutable
$localizedClock->now()->getTimezone()->getName(); // UTC

$localizedClock = LocalizedClock::new(new DateTimeZone('Africa/Addis_Ababa'));
$localizedClock->now(); // DateTimeImmutable
$localizedClock->now()->getTimezone()->getName(); // Africa/Addis_Ababa

$frozenClock = FrozenClock::new(new DateTimeImmutable('now', new DateTimeZone('UTC')));
$frozenClock->now(); // DateTimeImmutable
$frozenClock->now()->getTimezone()->getName(); // UTC
