Get timestamp for today's 00:00 Moscow time?

Question

PHP

The essence of the question is in the title. What is the easiest way to get unix timestamp 00:00 of the current day for the Moscow time zone.
Moreover, the current time zone in the script can be different, and it is not recommended to change it.

Answer 1

It may be useful to someone, I couldn’t think of an easier one

function GetMidnightTime($timeZone = 'Europe/Moscow')
{
    $d = new \DateTime(null, new \DateTimeZone($timeZone));
    $d->setTime(0, 0, 0);
    return $d->getTimestamp();
}

Answer 2

date_default_timezone_set
date('Ymd')
strtotime
