public static function RulesDateOffsetProcessor::applyOffset in Rules 7.2

Intelligently applies the given date offset in seconds.

Intelligently apply duration values > 1 day, i.e. convert the duration to its biggest possible unit (months, days) and apply it to the date with the given unit. That's necessary as the number of days in a month differs, as well as the number of hours for a day (on DST changes).

    // Get the months out of the number of days.
    $months = intval($days / 30);
    $days = $days % 30;

    // Apply the offset using the DateTime::modify and convert it back to a
    // timestamp.
    $date = date_create("@{$timestamp}");
    $date
