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

?>
