The offset accepts the ISO 8601 zulu designator (`Z`) as an alias for `+00:00`, with or without fractional seconds.

```php
<?php

declare(strict_types=1);

use TinyBlocks\Time\Instant;

$instant = Instant::fromString(value: '2026-02-17T10:30:00Z');

$instant->toIso8601(); # 2026-02-17T10:30:00+00:00
