    Example of converting between timezones using the DateTime and DateTimeZone classes.

    Note that PHP will also take care of calculating relevant daylight savings!

    <?php

    $utc_timezone     = new DateTimeZone("UTC");

    $tallinn_timezone = new DateTimeZone("Europe/Tallinn");

    // Create a new DateTime object in the UTC format

    $datetime = new DateTime("2023-01-01 11:00:00", $utc_timezone);

    // Convert the DateTime object to the timezone of Tallinn

    $datetime->setTimezone($tallinn_timezone);

    // Display the result in the YYYY-MM-DD HH:MM:SS format

    echo $datetime->format('Y-m-d H:i:s');

    // Returns: 2023-01-01 13:00:00

    ?>
